I have replaced the floor pans, cowl panel, outer rockers, outer wheel wells, quarters, all of trunk and inner and outer tail pans on a 70 camaro. I am just about ready to put it in epoxy primmer for body work. My question is when does all the seamsealer go on? Before epoxy, after epoxy before primer sealer, before paint or after paint? what is a good seamsealer to use ( like on inner/ outer wheel wells where they meet, rockers to wheel wells and cowl panel to cowl) Thanks for the help.
