What is the problem with my paint job ?

[renlaf]

I had a new paint job done on my vette about a month ago. Since a week or two I can see "bubble of air" appeared a few places.

That is for sure, I cannot have a true answer from the body man that did my job.

It seems to nobody that I know and ask questions about that problem, has an answer for that.

Is there someone around had that kind of experience and knows something about that ????!!!!!!*&?

Thank you in advance for the help !

Sounds like the fiberglass was contaminated with either silicon, or some type of oil. Perhaps the painter didn't clean the surface well enough. Where is it bubbling? If it’s the hood, near the AC compressor its usually in the past the compressor was throwing oil.

mine has big long bubbles right in front of the headlights were it wasn't cleaned right i would think. if is alot of places they didn't clean it right and only a month they should fix it!

I would say either the surface wasn't cleaned right or something contaminated the spray gun when paint was applied to that area.

Yes a lot of places on the front and on the sides .
So in conclusion it seem that the paint did not glued to the body because surface what not cleaned enough. Well I will go back to the body man with tears in my eyes just to test how sensitive his heart is.....

Thank you

Have you done anything....... or just leave it as it is. I figure that as far as I am concern, there is so many bubble all around that a new paint job is needed
Thank you for info

Hello Edmond

I have a 1962 that was painted over the winter. (Ithink we have different types of fiberglass) anyways the car sat in a heated garage for at least 4 months and the paint was fine. In earley april I pushed the car out in the sun and got large blisters in the paint. We cut open the blister only to find that the fiberglass had ruptured.

The sealer used was stuck like glue to the top of the fiberglass,the primer was stuck to the sealer,the paint was stuck to the primer.

What the best guess so far was that prior to sealing the car they wiped it down with some type of a solvent that wicked into the fiberglass,the car got painted and the solvents stayed dormant untill the sun heated it and that point it exspanded and could not come thru the paint and rubtured the fiberglass.

Good luck with it

Hi
I cut a few bubbles , there is no fiberglass rupture, just air.... I use a needle and try to press the bubbles the paint don't stick to the body and popout again after a while.
I can figure you have big problem too...... I suppose a new paint job as been done or will be. It seems as for me it has to be the ultimate solution.

Oh weel ........ thanks anyway and good luck to you !

well isn't fiberglass suppose to have a gel-coat primer put on first if theres bare fibers? i know the older vettes were gel-coated, not sure if our C4 were from bowling green? mine big bubbles are not the fiberglass coming thru.

dose your paint look like big fish eye? if it dose they need to re-paint or if they don't know how to paint non metal cars give you your cash back.

In a nutshell: Poor surface preparation.

The affected area needs to be stripped and SEALED before priming, then repainted. Keep an eye out for any other ares that may appear.

Hi renlaf..........Who did your paint?

I would say either the surface wasn't cleaned right or something contaminated the spray gun when paint was applied to that area.

BTW... How was the stripper junk recommended Edmond?

Contamination could have also come from solvents etc being absorbed by the fiberglass from a chemical stripper if any was used.

Len sent me a book that I'm reading up on. I just bought new injectors and I'm going to look at a ZZ4 cam and a set of ZZ4 heads this weekend in Lockport. If they look good, I'll pick them up. If I get that ZZ4 cam, I'll get some 1.5 roller rockers, if I use my stock cam, I'll get some 1.6 roller rockers because the springs can't handle the ZZ4 cam and the 1.6 lift.

I'm not worried about stripping the car because I'm sure my neighbor could help me with that. He's the same neighbor who claimed that he stripped a whole car on his lunch hour at work! :L Too many people want me to spend the $700 to get it blasted off but I have other plans for that $700, like coated long tubes.

Is it a base coat / clear coat paint job ? Is it the clear coat thats bubbling as some clears don't work well with mixing brands :ugh

Not to threadjack, but...

$700 is pretty cheap, dude. My current shop project (Black Light) is being stripped the old fashioned way....hand sanding. My bodyman is a bit "old school" when it comes to surface prep (sanding rather than chemical stripping). My next shop project (Blackbird - my dailiy driver) also needs to be stripped, due in part to the paint actually soaking into the fiberglass and lifting (previously repaired area and didn't seal it prior to priming). I had planned to fix the RR quarter and minor areas, then "scuff, seal 'n shoot", but it didn't work out that way. The car made the decision for me.

The paint topic has been beaten to death here (CAC), and of course people have thrown in their .02 about it, but I firmly believe in proper surface prep. No, you don't have to try for show quality, (it is easy to achieve, tho) but the OP's problem directly relates to improper preparation. The same will apply in your case. You're best served to save your $$$ and do it right. If modding is what you're after right now, spend your $$ there and then budget for paint (it's likely not going to cost any more if you let it go longer).

To the original poster, sorry for the attempted 'jack of your thread.

 

[Edmond]

The stripping part was the only part I'm going to do myself. I'll leave the prepping to the guy that will also paint it. He's done various muscle cars for my neighbor and they look very good. The guy works in a shop during the day but he does side jobs. He used to live in the neighborhood and he's a good friend to many of the residents here that have been her awhile. I trust that he'd do a good job.

balloun job,..... full of .........air, to say the least !

Hello "Tigmaned"

Five years ago I had my car painted and there was no gel-coat primer put on that I remember....... just what they call up here in Canada, a catalyctic primer, that is suppose to be to use for fiberglass !

Could this be call a gel-coat in U.S.?

Anyway at that time, there as never been any problem with the paint. Job was nice and beautiful for years.

Finally I shoul have kept the old paint.........what a shame now ! For sure I need the cash back and a new paint job.
