After decades, I've finally gotten my bodywork skills to what I consider an acceptable level. The question is when do you stop? We've all seen the beautiful metal finish skills of some here on the hamb, but at what point have you work-hardened the steel or ground it SO thin trying to get it just perfect. In cases like this wouldn't a thin layer of bondo be preferable to overworking the metal? I'm sure even these metalfinished cars see the bondo spatula before they go to paint. Should you just keep working the metal or is it preferable to go with an eighth inch of plastic?
