I'm in the middle of a "lick and a promise" body-on restoration of a 76 vette for my wife. I've done quite a lot of body and paint work in the past, but not very much in the last 20 years. I know that there have been huge improvements in paint technology since back then. A friend has recommended that I DA the body well, down to the gel-coat if possible, then use epoxy type primer, block it off, then paint with BC/CC wet sand and buff. There is a PPG shop close to me, any specifics as to selection and durability of their products? sealer required under BC? or just do the prep work and farm it out for paint?
