Gorgeous job. I love Day 2 stuff and you nailed it. I am a 2nd gen Camaro guy and never knew that 1st gens had gray primer on the underside that wasn't always covered by the b!ackout. I learn something new every day. I seem to remember that some cars( don't remember what year) would get gray primer from the belt line down to serve as material for the paint shop to sand out any blemishes. Is that true?
BTW,as much as I love your car,if it were mine it would have Ansen Sprints on it.
