If it is an SMC bodied car...I use polyester primer and have had no problems ever with doing so.

Thanks! Being a 71 and looking at the back of some of he panels I assume it is a SMC car. what grit of paper should I end up with. can you recommend a brand or part number of what poly primer I should use?
Thanks again

Unless body panels have been replaced, most of a '71 body is not SMC.

I've been told that on a '71 only the rear quarters are SMC. The process was new, and GM started with the quarter panels.

The rest of the car is polyester resin.

front fender had been replaced. wheel well opening not correct. too close to the tire in front. I will replace the entire fender when I get it on the frame.

HONESTLY...I would STOP and NOT grind out the seams at this point...because ...as I wrote....HONESTLY..... this Corvette is not stripped.

In my opinion...which I know was not asked for...BUT before I would do any body work and grinding..I would have to get the body down to BARE panels and NO primer. And as always...its your car...do as you like.

And...there would be a limited amount of work I could do while the car is on this body dollie. Attempting to perform panel alignments and getting them right and or replacing panels....especially the front fender CAN ...possibly come back and HAUNT you.

I do not install some panels when the body is NOT on the frame. Mainly because ...I have done it and GOT seriously screwed by doing it. If you choose to do so...I hope all comes perfect.

In post #13..the first photo...you can see that the top hood surround is NOT a light gray...which means it is NOT SMC...for all those who may wonder how to tell.

In POST#12...the light gray fender section IS SMC.

aircraft paint stripper didn't seem to take the primer coats off, should I hand sand it off?

YES...carefully...obviously. See how well that goes....if you feel that you are wearing yourself out. Apply a little bit of the aircraft stripper in a test spot and use ROUGH Steel wool and scrub at it and see if it comes off some more.

CRAZY...you can USE Aircraft stripper but cannot get VPA...does NOT make sense AT ALL....the Aircraft Stripper with the Methylene Chloride (MeCl) is really bad stuff....and is actually on the list of 'things' the EPA has in the 6H rule.

I get the stripper from a mom and pop hardware store (I don't ask where they get it) and I can get VPA from a friend who does artistic painting on race cars and somehow can get the good paint (I don't ask where) and can occasionally get me some VPA. I only buy one quart at a time because of the shelf life so that is why I was asking about Rage but I won't go that route.

Aircraft strip does not take off the factory lacquer primer, so what you have is expected. DUB is 100% correct, you are not done stripping. The way we got the primer off mine was with brown scotchbrite and liberal amounts of lacquer thinner. Pour the thinner into a bowl or bucket, dip the scotchbrite in it and keep the panel very wet.

Here are some pics of what the panels should look like after stripping.
