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.

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.



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




Next we removed all of the mechanical items; engine, gearbox, tail shaft, leaf springs, differential, fuel tank, brake and fuel lines.




The front sub-frame was then removed and the body was supported by axle stands before mounting onto the vehicle rotisserie.


Vehicle Rotisserie



Following the disassembly of the vehicle, we mounted the body on a rotisserie and commenced the assessment of the vehicle.



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.
