Once corrosion starts between spot welded seams, it is difficult to stop it without removing and reassembling panels. You can ensure that it doesn’t start though, by coating the panel edges with our Zinc Rich Primer prior to assembly and spot welding.
The high zinc content of our coating prevents corrosion and ensures good electrical conductivity for welding.
