Toyota 100 Series – Front Windscreen

RE:     Toyota Landcruiser 100 Series –  Front Windscreen Aperture (Corrosion Repair)

This document has been prepared with photographic illustrations to highlight the severity of corrosion damage and the recourse of the repairs conducted.

1.0           Initial Inspection – 22/01/19

On the 22/01/19 @ 20:30pm, an assessment was carried out to determine the extent of vehicle damage and to enable an estimate for the repairs to be carried out at the clients residence. From the initial review, a preliminary rectification schedule was compiled and estimated (the basis of the repair scope and estimate was the use of lead filler and two metal plates to fill the large void areas). The photo below illustrates the conditions at which the assessment was carried out (at night and under insufficient lighting).

2.0           Vehicle Review – 24/01/19

The vehicle was delivered to the workshop on the 24/01/19 at 09:30am. The vehicle was reassessed under better lighting conditions and the following observations were noted. The photograph below illustrates one of the void areas where the level of corrosion damage was more significant with the corrosion penetrating through multiple layers of the windscreen aperture.

3.0           SCOPE OF WORK

From the condition review/reassessment conducted on Thursday 24/01/19, the following scope of work was conducted to meet the basic requirements of the repair and return the structural integrity to the panel section.

3.1                Turret Aperture

In light of the condition reassessment and scope requirements, a complete new panel section was fabricated to match the original profile. The fabricated panel was then trial fitted for the correct contour and alignment.

Note: the multi-layers of corrosion build up beneath the aperture were obstructing the correct alignment of the replacement panel, so the complete lower lip of the aperture was removed.

10

Upon removal of the windscreen aperture section, the internal support frame was found to be weakened by the corrosion. The area was sandblasted to remove the corrosion contaminants and clean the metal surface ready for welding.

11

The panel replacement section was aligned and held in position by clecos and then fully welded.

3.2                Vertical Apertures

Both of the vertical apertures were found to have localised areas of corrosion around the perimeter of the (pillar trim) fixing holes.

7.jpg

The full lengths of both apertures were sandblasted to remove all of the corrosion contaminants.

4.0           Conclusion

20190131_101430[1].jpg

The remediation of the corroded turret section has been completed above the standard of the quoted repairs. The requirements have resulted in time/cost variations which we have absorb to preserve the integrity of our fixed price guarantee.

LHR Fender – Repair

This video illustrates the repair process on the rear fender of a VW Beetle Convertible.

The cracks that were visible in the fender panel were the result of a failed attempt to repair a vertical fracture. The extent of the damage was assessed and a new replacement panel was fabricated to the size required. The damaged area was then cut out completely the new replacement panel was aligned and fully welded.

1957 Chevrolet Bel Air

Rear C-Pillar Restoration

This Chevrolet BelAir had significant corrosion damage in both of the rear C-Pillar’s. The repair process involved the removal of interlocking panel sections which provide the structure. The surface was cleaned free of contaminants and etch primed. The sections removed were re-fabricated and the structure repaired from the inside out.

This vehicle had the appearance of a very tidy unit albeit for a couple of minor issues at the rear wheel arches that raised concerns.

To investigate the hairline cracks and irregular contours, we started by removing the surface duco from the left hand side (LHS) quarter panel. Beneath the surface was an excessive amount of body filler that in places measured over half an inch thick. This was followed by an additional amount of fibreglass in the rear wheel arches and internal tubs.

Now back to bare metal, the assessment of the LHS quarter panel concluded that there was excessive panel damage and extensive corrosion damage in the internal and external sections of the wheel arch. Given that there is a readily available supply of reproduction parts, It was determined that the most efficient course of action was to replace the complete external skin and internal wheel tub.

Next the right hand side (RHS) quarter panel was investigated and it too was concluded to have been repaired the same way as the LHS quarter panel. The repair schedule was set to include two new quarter panels and also new internal wheel tubs.

The doors both had new external skins replaced, the internal frames were sandblasted and minor rust repairs conducted. The complete front window aperture was cut out and replaced by Rene Farrace. And other repairs included the firewall, the RHS turret and drip rail sections.

The owner wanted to convert the vehicle to LPG and provided us with the pressure vessel. The brief was to have the tank in the boot of the vehicle, but also to retain as much boot space as possible. The boot floor was re-fabricated with the vessel recessed in to it, this lowered the compartment floor level and provided the function the owner required.

This vehicle was delivered in a metal finish ready for paint.

Mustang Fastback

Lead Wiped Repairs

The rust repairs/restoration of the Mustang door pictured here has been repaired by a technique called lead wiping. At Auto Resto we are passionate about providing quality repairs and this is why we still practice this old art. This is our way of providing a budget friendly solution and still maintain the quality of a metal finish.

This Mustang is a fine example of a picture perfect vehicle. Although there were some major issues with both the driver and passenger doors. The corrosion in the lower sections of both doors were so bad that they had to be removed to be repaired.

This slide attached illustrates the Mustang door removed from the vehicle and the internal mechanisms completely disassembled. The next step in the process for this door is for all of the corrosion to be removed by abrasive cleaning. Hence the reason why the door is just a shell.

Although sand blasting is the best method to completely remove all of the corrosion deposits, the process can create issues far beyond just the repairs required. For example, if the door mechanism, glass and window regulator were left in the door, the fine grit would penetrate into the mechanism and fowl the operation. If the abrasive made contact with the glass, you can kiss that good bye too! As laborious at it might seem, prevention is far more sensible than the grief, time and cost and of locating & replacing damaged parts or components.

At Auto Resto we pride ourselves with providing quality solutions that endure the test of time.

The photos illustrate the Ford Mustang firewall conversion to right hand side drive .

The old firewall was used as a pattern which was inverted, re-fabricated, aligned and fused welded in place. The process included the relocation of the heater box and the location of the inlet/outlet hoses.

The brake booster was then re- located and the firewall was recessed to provide clearance and the correct placement of the pedal assembly. The steering column was then aligned with a protrusion was made through the firewall and secured with a bespoke end plate.

The repairs were then sandblasted and etch primed to seal the metal surface from atmospheric conditions during the restoration process.

Honda Prelude – Rear Window

At Auto Resto we are all about corrosion remediation. Although 80% of our work is vehicle restoration, we also repair corrosion in modern vehicles too.

Just like this Honda Prelude, window rust is a common problem for many vehicles. There are multiple reasons why this situation has occurred, but the obvious is the build-up of decaying plant matter.

The build-up of vegetation has retained the moister long enough to permeate through the surface coating and with the assistance of readily available oxygen, this has created localised corrosion cells.

As illustrated, the extent of corrosion damage was so deep inside the metal structure, that the contaminated section had to be completely removed and duplicated.

The fabricated repair section was then fused welded in replacement and sanded off to a metal finish.

Holden EJ – Fender

Holden EJ – Fender
This fender belongs to an Holden EJ Ute.

Sometimes a clients budget needs to be staggered over time and we don’t always get to see the whole vehicle all at once.

This fender had some minor issues in the past which could have been repaired better by the other repairer. At first sight, the corrosion appeared to be concentrated at the lower rear section of the fender.

The fender was then sandblasted to remove the paint and corrosion contaminants.
After the blasting process, the fender was reassessed and we found that the upper rear section of the fender had a small concentration of corrosion perforations.

Rene created a pattern of the fender sections and then fabricated the complete external (rear section) and lower internal fenders sections.

The corroded internal & external fender sections were then cut out and the replicated panel sections were fuse welded in place.

This may seem to be an extreme approach, but at Auto Resto we warranty our rust repairs for 5 years. We are passionate about restoring vehicles and eliminating corrosion.

Buyer Beware

This Holden HR Ute was purchased as seen above with little knowledge of the underlying issues yet to be revealed. This vehicle was sold on a club licensed and when the new owner tried to re-register the vehicle it failed for good reasons.

Disassembly

The vehicle was then totally disassembled. Everything was remove from the vehicle, the interior, the windows, doors, fenders, headlights, grille, the front bumper.

Vehicle Assessment

A preliminary assessment was conducted on the vehicle to re-evaluate the areas of concern. We’ve provided a brief extract of the findings, as continues.

LX SS Torana

 

Condition Assessment

Yes this is Ron’s LX SS Torana, as it was in poor condition but full of potential. With a mammoth task ahead, we started by assessing each of the key areas requiring attention and compiling a checklist over 30 items long. After which, each item was further broken down, identifying multiple tasks required to achieve the repairs required. All in all there over one hundred (+) items listed before the restoration begun.

The vehicle was missing a lot of metal, mostly because of the extent of corrosion. The previous repairer removed the right hand rear (RHR) Quarter Panel and lower rear valance panel. The right hand (RH) Rear Bumper fixing tubes and the vertical portion of the chassis rail had also been removed.

The external cover panels of the left hand (LH) & RH C-Pillar sections had already been removed by another repairer. The internal extrusion of the left hand side (LHS) C-Pillar was entirely corroded from the turret to the base of the C-Pillar / Quarter Panel interface point. The LH Rear Window sill was corroded through to the internal section.

Due to the excessive amount of corrosion activity at the LH C-Pillar point, the lower rear quarter panel section became corroded and severely fatigued. The rear turret section (which meets the hatch door) was still intact, but was in desperate need of repair.

The rear beaver panel had corrosion along the top section of the panel, above the both tail-lights and also beneath the rubber seal channel section.

LH Front A-Pillar

The A-Pillar section of any vehicle forms an integral part of the structure. The corrosion damage illustrated in this vehicle has extended beyond the immediately visible areas and into the overlapping structure. This requires each panel to be removed individually (like an onion layer) until a sound metal structure is found.

The A-Pillar section presents another challenge, where it serves to support and align the corresponding panels around it. The complexity of this section is further highlighted when we tied the upper Window Pillar section with the lower A-Pillar.

LHS Fender

(LHS Fender – Repair)

The corrosion damage in the lower rear section of the fender was only visible by a small perforation. At closer inspection of the damage it was identified to be significantly larger than originally estimated.

The lower corrosion damage had been previously repaired with fibre glass and this was concealed by the black primer which was applied after the owner had it sand blasted.

Furthermore the previous rust repair was only performed on the external panel section and the internal section was left without being repaired.

Radiator Support Panel

Following the repair to the lower fender section, we repaired the lower section of the radiator support panel to ensure the correct alignment of the (front-end) body panels. Again the owner supplied a near perfect replacement section which we aligned and fuse welded in position.

LH Rear Quarter Panel

The lower rear section of the left hand quarter panel and the wheel arch had excessive corrosion damage. The cause of the damage was due to the extensive corrosion perforation throughout the internal and external sections of the LHS Rear C-Pillar. The donor section was provided from another vehicle and again in near perfect condition.

LH Rear C-Pillar

This video illustrates the restoration process of the left hand rear (LHR) C-Pillar. As you will see the corrosion damage had penetrated extensively throughout the C-Pillar structure. The process involved removing each layer until we found a solid base to start the repairs.

Each section was individually fabricated and fuse welded to achieve a seamless integration. The only exception was the external C-Pillar cover panel which was purchased by the owner. However, this panel was short of the finish length and required modification to complete the interface joint between the C-Pillar and quarter panel.

The fabrication work was finished the same as it was from the factory and as close possible to the original.

RH Rear Quarter Panel

When the vehicle arrived the RH Rear Quarter Panel had already been removed. There was some panel damage to the RH rear wheel arch which needed attention before the replacement panel could be fitted.

Another issue that presented itself was that the replacement quarter panel that was supplied was not the same model, it was for a UC Torana Hatchback. Nevertheless, we aligned the replacement panel, marked the required section and trimmed away the excess.

LX SS Torana

Prior to welding the quarter panel, we had to repair the wheel tub damage, align the body panels and then trial fit the quarter panel.

Auto Resto

During the trial fitting, it was noted that the hatch tailgate alignment with the beaver panel was out of alignment. This is illustrated by the photo above, the horizontal gap tightens as it meets the vertical point (gap) of the quarter panel.

RH Rear Tail-Light & Beaver

LX SS Torana

With the RH tail-light fitted, it’s clearly visible that the tail-light aperture is out of alignment. To rectify the excess spacing between the light and the tailgate aperture, Rene split the body section and added approximately 5mm of replacement panel.

Auto Resto

Although the alignment issue was rectified, the panel section above the RH tail-light still had to be replaced because of corrosion fatigue.

Auto Resto

Rene Farrace fabricated the replacement panel and removed the damaged area.

The replacement section was fused welded and metal finished.
