Is this the entire frame and body panels???
Epoxy primer will hold real good. I'd still keep a cheap tarp over it just to keep it clean

Can you shoot primer? My neighbor paid $335 to get a chassis blasted and all panels but the hood blasted. Then he rolled it across the street and used my place to spray epoxy on it. You can do body work over the epoxy.
Location may mean a lot as far as price goes.
I'm sure others have more experience than me and will chime in as soon as they get back from taking the misses to the moovies!!
