Or whatever the substance is anymore. Not sure if "leading" is EPA approved but whats its' replacement? Is anyone doing it? I have thought that IF I build an old style street rod{ever}, I'd like to smooth the seams. Is it easier to just use mig,tig or the body panel glue. I like learning to do new things. I need to learn to Tig aluminum but I'd like to learn the lost arts too..





Even if you lead a body seam you need to weld it or it will crack just as any filler would. Working lead takes practice like any skill. Done properly it will last a lifetime. Done poorly it is no better than plastic fillers.
