i put por15 on mostly the rear end of the body. from the rear floor pans, back to the tail panel. had the rest blasted.
wiped all the bare metal with lacquer thinner and coated everything in DuPont varaprime. as for the primer, i used something
from DuPont, can't remember the name, but it didn't need to be wet sanded. once the primer was on, i scuffed the whole
underside, trunk, engine compartment, basically everything that needed to be cut in, wiped it down with prepsol and then
painted and cleared.
