It was a rattle can job iirc. About 20 cans of it lol.Man awesome build. I wish I had more to read though! I sold my mustang for a jeep a couple months ago in preparation to have a car I can pull apart like yours. My first car was a '94 5.0 and I want to have something like that again. I'll be following this build as inspiration until I find the platform for my build. Also I'm from Joplin, MO but left 5 years ago (navy) now I'm in Hawaii
Also when you were shooting your car with primer and doing the undercoating, was that a rattle job or do you have a gun you were using? I'm interested in doing something very similar to your build that you are doing so I just want to see what I'd be up against.
