Can anyone help me out on this. Im in the middle in re building my bargain saph cossie. The car was a total dog and the previous owner left it for a year rotting in his drive ,but i felt the need to bring it back from the dead rather than strip it for parts. I have spent the past 2 months working on the engine and the electrics. The last job is the body work. Last weekend i hacked off one of the front wings ready for its new replacement. I have undersealed the new one. But i was wondering once i have welded it on can i primer the wing with spray can primer. I have herd from a few people that spray cans contain silicone and that this reacts to normal spray paint.i need to protect the welds with something..... Can anyone help me out on this?
