Default removing primer?

I just started stripping paint of my vette. I am using chemical stripper (Captain Lee's Spra' Strip). It removes the paint pretty well, but not primer.



What is the best (fastest and safest), way to easily remove primer? I was using orbital sander with scotch brite pad but is very time consuming.

Any ideas?
S.

220 grit wet sanding using a flexible block ought to get it off there. It will also help assure the stripper is fully neutralized, as well as starting the process of flattening the surface. There is no easy, quick way to remove all the paint yourself.

Everyone seems to have their own way. We used scotchbrite and lacquer thinner on mine. Yes, it's hard work.

If the primer is in reasonably good shape, leave it. Saves you a lot of work.

I disagree. I would never leave 30-40 year old lacquer primer under an expensive urethane BC/CC.

I use scotch brite and laquer thinner. That has worked the best for me.

I disagree with Easy Mike as well. If it's original to the car it is lacquer based and has certainly shrunk considerably as lacquers are wont to do so it isn't stuck to the glass as well as once was. It might not be (probably isn't) chemically compatible with whatever you're about to put on top of it, like Zwede said....if it "blows up" later you'll be out all that time, effort and money. I understand your wanting this to go faster and simpler, but I did not and would not skip a "full strip" if I removed any paint at all.

I'm using a razor blade to get the old lacquer paint and (then in the .70's what they called epoxy) primer. IMO, Corvette repaints demand total removal of all paint/primer/sealer down to the bare glass - unless you want problems down the line (or when you lay on the new paint). The only stripper I like is the gal I saw outside of Savannah, Ga. in 1968 or 1969 - other than her, you had better make sure none of it seeps in the glass.

The original factory primer was baked on and there's no good reason to take it off. It's going to get covered by a sealer coat anyway.

Call the paint manufacturer's tech line and ask them. They'll steer you straight since our opinions seem to vary. Do whatever it is they require.

If the factory primer is in good shape, their is no real need to strip the body to bare fiberglass. Any good quality primer/surfacer will seal the original primer.

Who is painting the car? You or a professional? If you have having a pro paint the car, then the advice from markids77 is good: contact you painter and see what they have to say.
