964 kidney bowl rust repair - Rust repair isn’t about hiding corrosion — it’s about eliminating it.
At Autobody Technic, we believe in repairing cars properly, which means removing all affected metal and using repair sections. If repair sections are unavailable then we do have the correct knowledge and tooling to fabricate our own sections. Anything less is simply a temporary fix.
This Porsche 964 arrived with severe corrosion in the sill area, a common problem on these cars due to years of trapped moisture and debris. In fact, it’s one of the worst examples we’ve encountered.
The photos show the process from corrosion removal through to fabrication, welding and primer. The repair has been completed to a high standard and is built to last for many years to come.
We start with making a template for us to fabricate a new repair sill section as this is unavailable
We’re cutting out and looking deeper into the car to discover more corrosion
The affected areas are cut out
New pieces are fabricated and welded into place
Welds are then ground down to make a flat surface for the kidney bowl to sit
Preparing the surface for the kidney bowl to sit
New kidney bowl welded into place
Protecting the kidney bowl with an epoxy primer to help prevent any corrosion in the future
New sill section welded in
Now the structural work is done we start closing it all up, starting with the door shut
Carefully realigned and held into place
Door shut is now welded in
Door shut welds are ground down and the quarter panel is reassembled
