Good evening everyone, I'm restoring a vintage car that has some corrosion points (rust) inside the overlapping joints of the sheet metal, nothing serious but it is present. On the inside of the body I tried to lift the metal near some spot welds and I noticed that practically every spot weld has a slight ring of corrosion around the weld itself despite the fact that the cataphoresis went deep inside. Is this corrosion caused by humidity and therefore crevice corrosion or by a bad cataphoresis process? If I had to proceed with paint strip, acid bath of the entire body and subsequent cataphoresis, is there a risk that the acid remains trapped in the overlapping joints which have a very limited gap or will the final rinse reach every crevice? I'd like to do a definitive job but I'm stuck at this point
Thanks
Thanks
