Sort of a 4x4 rat rod. Simple, cheap, basic & effective. That's a hard combo to beat. It's something that almost anyone can do at home without needing to shell out $3K to a shop.
I did some concrete work last fall for a guy that does auto body repair. We had a few beers and I picked his brains over what I needed to do.
Basically, I spent half the day masking around the windows, bumpers, removing the grill and headlight bezels, taillights and mirrors. Prep was simple, wash, dry, then scuff it with a greenie pad soaked in xylene. Dab in some rust-x to chemcially stop any rust, and some weather seal adhesive to fill in the pinholes.
I rolled on the first coat, that took about 2 hours and a gallon of paint. That's where I left it for the first day. On the 2nd I used up another gallon and laid on a 2nd coat, then touched up a few little places with some stain brushes. about an hour later it was tacky to the touch, and I pulled off all the masking, then went around with another touch up coat, and did the insides of the door (around the hinges and door stricker / jambs.
I rolled on a 3rd coat on the leading edge of the hood, along the rocker panels, and around the fender wells, thinking those areas would see the most abuse.
Two days in a garage, and this is the result. I'm pretty happy with it.
If you can slap paint on a bedroom wall, you can do this.
