!981 Corvette with bad paint

I recently picked up an 81 vette for 5k but the paint on it is terrible. Someone has repainted it and it has several large blisters in it what is the best way to fix this?

Well I won't be on your Xmas card list when I'm done but here is your answer.

The bubbles is why you only paid $5000 for the car, rule for last 50 years on vettes is factory paint, one repaint and then must strip.

So the bad news is your car must be stripped, no if and no buts about it, a place that does work on vettes and knows how to fix the right way will cost you $8000-16,000 for the strip and paint.

If you are unlucky, you will find a regular shop that has never done a vette and they may price the job at 4-6,000 dollars because they think painting a vette is same as a metal car. RUN SCREAMING!

I'm being a little blunt here but the problem happens every day and people do pay the 6,000 and within first month it is bubbling again and the shop won't honor the job, hear about it once a month anyway.

Now is the time to learn to do paint and body work or you will end up with a $21000 nice looking 1981 vette.

Is it just the hood? very common on the hood,,sometimes getting a used sound one is better than fixing it if it's just on the hood, those bubble troubles run deep and take some technical digging and filling to repair..

Can you post a couple pictures?

This is exactly why you cannot have a vette done by someone that does not know vettes!

The bubbles 99% of the time is coming from excessive layers of paint that expand at different rates along with the expansion of the fiberglass/smc also.

So you buy a used hood and strip that when all you have to do is strip the hood on it? You just blew $850.
There is no digging and filling 99% of the time.

this is what happens when you let some shop monkey get their hands on a vette. no idea how to do it but they know all. each and every step done wrong and the end result is what you have. i can promise if you let another hack repair it you will have an even more expensive bubble and nothing but excuses . media blast it and epoxy it, then paint it .
do not use chem strip ! razor blade and sand it but use no chemicals.

I've seen this too. Not sure what it is but Barry mentioned expansion rates and that makes a lot of sense. The only other thing I can think of is fiberglass wicking in solvents and then turning into a gas later.

Vettes should not be chemically stripped and people think that's the way to go. They can't be blasted with anything too hard either or it will look like swiss cheese. Soda blasting works but can't say what's the best way to strip them as I don't have extensive experience with fiberglass. I'd make sure the blasters are well aware of how to blast fiberglass.

Of course you could block sand the paint off with a grit that's easy on the fiberglass but you run the risk of changing the shape and if you don't block good it can mess up your shape, but if you block good you'll probably be sharpening it up at the same time as fixing your problem. Bottom line, best to wait til someone responds who has extensive experience with fiberglass.

i use type6 acrylic to strip with. works good and does not tear up the glass. no soda on porous glass for me. most any bubble is gassing. cleaning with lacquer thinner is the fastest way to get one. i clean glass with soap and water and give plenty of time to dry out.

This is a great response and had a feeling it was outgassing. Is acrylic 6 a blasting media or a chemical stripper? I'll copy and paste this response to a word doc for reference.

type 6 acrylic is not a chemical . it is a plastic media . not just any blasting place can handle glass. if not then heat gun and razor blade.

chem strip - dissolves the resin and allows it to scrape off. also leaves behind a mess to soak into glass. then lacquer thinner is used to wash off the mess and the red lacquer primer. this melts it all together and soaks it into the glass . new paint job after a few days in the sun and you have new bubbles to deal with.

So I take it a $1995 silver Vette with bad paint won't ever look better than it is without a huge investment?

Why can't I rattle-can it silver? I'm not looking for show quality, just cover up the yellow spots.

Doesn't take a huge investment. It just takes doing it RIGHT! Sorry but rattle can isnt going to make it look better!

i would rather have the car like it is in that pic, than have rattle can paint all over it. sure it may take your eye away from the yellow but it just creates more problems down the road when there is a potential for a new paint job.

to the original op. if it is on the hood or any other sole panel, sooner or later it will be everywhere else. i try to tell guys that all the time with vettes and for some reason they just dont want to listen. they end up having the hood or fender spotted and next thing you know 6 months down the road another place shows up on the roof or quarter.

i havent done a vette, strip and paint, for under 12k, and that was a cheap one. like said before...vettes are just a different breed for paint and body.

Looks like someone has started sanding this one already.
I've painted much worse looking ones than that; all you need to do
is finish sanding the paint off, apply an appropiate primer, block sand
and then topcoat. It's not rocket surgery.

If you're going to do it yourself, check out some boat forums for tips.
A Vette body is nothing but an inverted boat hull.....
