I have a 1987 mustang. The car was factory acid dipped at the ford factory, so its 1980’s enamel paint.
I need to repaint body panels.
Please help me with the process:
So I am looking at the door and it is blue factory paint. I begin to scratch it with large grit sand paper. Now it is covered with large scratches and I begin to see grey factory primer. Do I stop with the sanding? Or do I continue untill I see mostly factory grey primer with shiny scratches? Do I stop then, or do I continue untill I see mostly shiny metal and some gray factory primer?
I dont want to remove all of the paint and factory primer, exposing the bare metal. I’ve heard that at the factory primer galvenizes the metal, or the metal itself is galvenized, and scratching the factory metal will remove this protection and make the door more suseptable to rust in the future after it is repainted.
