It was around $1000 a couple of years ago, to do the body, fenders, doors, hood.rear valance. It removed all the old paint, rust and bondo. They had it for about two weeks from the drop off time to pick up time. You will need to treat it the day you get to stop flash rust. I think it was phosphorus(?) that I used and then coated it with etch primer. It worked for me, others maybe able to suggest other ways/products to cover the bare metal. I'm not a body or paint guy, this my first time with a project like this.
The shop across the street is or was run by a guy that was involved with a Super Stock Barracuda back in the day. His wife drove it. I think he did a small block for the engine challenge that one of the magazines do every year.
