Post pictures of progress, would be interesting to watch it has it evolves. Being that vettes are fiberglass, it is gonna be a slow process to do it right. If you get to crazy with an orbiting sander , ya gonna put flat spots n it and it will come out looking like a golf ball.

What are you trying to accomplish? Are you trying to strip it or just sand and repaint? If you are just sanding and repainting you should sand with 320 grit and then use sealer and repaint. Give us some more to go on and we can help.

Welcome to the club! Not many people attempt this. When I repainted mine years ago I was amazed at the factory paint on the car. It seemed like when I first got it it would easily scratch at the mere mention of anything sharp, but then would almost laugh at me when I was using some aggressive sandpaper to puposely remove the paint. Never really understood that. It's rarely fun, but never boring, stripping a car. Keep at it, and send in some pictures of your progress. Good Luck!

Dual Action Orbital will help with this problem and speed, but as others have said, we need to know exactly what you are trying to accomplish, factory paint or not, condition of the paint, etc.... to make a correct recommendation.

I hand sanded my first vett, a 62, never again, I'd strip the whole car first. They have stripper that is safe to use on our plastic toys.

i am getting all of the old paint good enough to repaint. i wrecked it about a year ago and i have been redoing the whole car since then. i have used a power sander to get it down a little but then i hand sand the rest. i dont want a body shop to do it because i dont trust anyone else with my car(i know im paranoid, plus ive been f'ed over a lot by shops). i also dont want to use a chemical because i dont feel safe with it after the new paint is on.

btw, i have been taking pic's the whole way and will show the finished project in about a month when im done.

I painted my '88 back in April. Sanding and prepping the car was not a bad job because I had very little bodywork to do (minor repair on drivers side rear fender) and I was just doing a repaint of the same color. But, I'm sure I spent at least 40 hours color sanding and buffing the clear...worked on just the hood for two days before I was satisfied. It just takes time and patience...

Exactly why a body shop charges so much for prepping. It's not easy or quick to get a good job.
The only thing I can recommend is to use lots of water. I like your pictures... take your time and it can turn out good
A nice paint job is based entirely on the prep work.

Here is mine, took freaking forever... but I am very happy with how it ended up:

I hate to disagree but the fibreglass stripper is NOT safe to use on our cars. If left on too long it will damage the surface, especially on the urethane bumpers. I did mine just over a year ago and I can relate to your feelings but keep on doing what you're doing, you'll be glad you did. I had mine painted black and the results have been VERY satisfying.

It looks to me like there was some garage engineering going on, maybe to remove a stuck lug nut?

I was a body and paint tech for 15 or so years. Stay away from Chem stripping, glass loves to absorb harmful stuff. For the first year and a half of owning my own shop I Specialized in Vettes. The easiest safest way to get the old paint gone is to media bead blast. Soda and walnut blasting works good too. It takes it down to the gelcoat without damaging the glass or previous body work. It was running around four bills to have the process done. You drop off the car and pick it up in just a couple of days and you get to see how good of shape your car was in.
Also if you happen to be priming try to use a catalist base waterborne. It keeps any reactions down to a minimum and is safe with any system of paint, as long as you use a sealer first. plus if the five-o- shows up to the house because of paint, you can show them it is a water based product. Helps to keep the fines away.
