Default my paint has blistered

Hello everyone
I just saw that my paint has blistered. I bought it this summer, the paint is nickel (well, at least there were no blisters).
It is parked in my garage which is quite humid in winter, I wonder if it is not because of this humidity that the paint has become like this. In any case, it's very ugly, I'm going to have to go through the paint box.
But before I would like to be sure of the cause to avoid it happening again.
Do you have an opinion on the matter?
thank you and good evening
Alexandre

FWIW: I think your problem originates with contaminants in the undercoat.

I have the same thing with my '79. It has had one repaint base coat/clear coat. I think it is from contaminates under the color coat of the second paint job. I've also read where it could be moisture that was trapped in the fiber glass prior to painting (second time)....... It has lasted over a year now without buffing with a machine. Only by hand.......

I didn't stay at a Holiday Inn last night but looks like poor prepping from the last paint job your car got.

A quick question: was the car painted right before you bought it (I'm assuming it did not look like this when you purchased)? I can tell you without question, that this is not caused by humidity. It's poor prep, contaminants in the primer/base/clear coats. There is only one solution, and your aren't going to like it. Really sorry. Best, Paul

You will need a number of products to do a paint job correctly. Read up on the subject and gain an understanding of what you plan to undertake. It can be done by an amateur but there are a LOT of steps involved.

Do you have any idea of when the car was painted? What type of paint? What kind of primer? Did the car sit in hot sun for a long time?

Suggest you call Southern Polyurethane Inc or SPI in Georgia and ask for suggestions.

Was the car ever covered. I've seen this happen when a car with a car cover is left out in the rain or in high humidity and not uncovered once things dry out.

Moisture in the airlines when the car was painted, will over time cause small bubbling. As others have mentioned, there can also be other causes. The only way to fix it, is to sand off the layers of paint, to below the bubbling. Depending on the quality of paint below the bubbling, you may not need to sand down to the bare fiberglass.
There are lots of opinions as to what products to use to repaint the car.
If I was repainting it, I would first spray an epoxy primer which will bond to the remaining paint or bare fiberglass. The epoxy primer is normally not sanded. Then apply coats of a urethane primer/surfacer that is sanded as needed to get a smooth surface. Some painters apply a thinner mix of epoxy, as a sealer over the primer before applying the base coats. Then apply the needed coats of base coat for good coverage, followed by several coats of clear. If the car is going to be water sanded, then additional coats of clear will be needed.

As you are located in France, I would use whatever brands of high quality paints are available in your area.

Akzo Nobel Sikkens is the #1 automotive paint manufacturer in Europe. If you are interested in learning how to tackle this yourself, I’d make contact with a local representative who I am sure will give you the necessary guidance for the finishing materials that will comply with European regulations. I’ve used Sikkens products here in the USA and was pleased with the results.
