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.
