Most likely the existing paint wasn't compatible with the new paint. If that is the case he may say sorry about your luck. That is a very real concern when painting these old trailers. What you may be seeing is the old paint off gassing and causing the new paint to bubble. It is hard to diagnose without seeing it in person.

It's a problem with prep. Will need to be stripped and repainted.
Problems like this happen all the time, even to the best painters.
It's the reason they will not paint a "high dollar" automotive paint job over existing paint/primer, unless they are paid to take it all the way down to bare metal, and then control exactly how the primer/sealer/paint/clear coat is applied.
Sorry

LOL, I'd tell him "I was sorry about his luck" after poking him in the eye!
If he's a professional painter he should know what paint "is compatible", what "can be sealed", and what "has to be" removed for a proper repaint.
Just my opinion, LOL

Bigbill and John Palmer, there was no existing paint. I stripped it all off myself down to the bare metal. He was supposed to clean the aluminum, prime with self-etching primer, and paint with Sherwin Williams single stage enamel (automotive quality).

I went back and posted some pictures of the paint and primer he used, and one photo of the bubbles. Anyone? Also, here is one photo of what it looked like before paint.  |

"supposed to clean", maybe he did, and most likely he did!
But it was not entirely clean when the paint when on or you would not be having this discussion. Have you ever worked around a body shop and seen all the dust blowing around. All it takes is for the wind to blow some sanding dust on the surface just before he shoots the color coat on and you will have the adhesion problem you have described.
I heard about a friend that had a automotive paint problem because someone started a diesel truck next to his car before the final coat when on and the diesel oil caused the contamination bubbles.
Was the trailer painted inside a spray booth, or painted outside? The "hot shot trailer painter" in So Cal paints his trailers in a barn, which is far from dust free area, like a quality down draft spray booth.
He'll fix it, and it will be fine, sorry for your hassle. If you have a problem, take it by a good (automotive paint only) Sherwin Williams paint store and have them look at it for a second opinion.

The trailer was painted inside in a paint booth. I hope he fixes it!

I hope so also. Diesel exhaust was mention that causes severe fish eye and that isn't your problem. I you get lucky since it was over bare alum. maybe the paint supplier will eat the cost. If the primer wasn't cured before the top coat was applied that may be your problem. It will be interesting to see what they say.

Bill, I can understand a manufacturer/distributor/dealer would be interested in taking care of "a product related failure" as maybe goodwill, but why would they cover a painter's "application issue"?
I agree, it will be interesting to see how this plays out.

John If they decide it was the painters fault they won't unless he is a high volume customer. A lot depends on the paint shop and what they promised going in, and their desire to do what is right. Since this is mostly on the top it is also possible that the paint was exposed to an outside chemical such as some types of tree sap or fuel dumped from an aircraft or who knows what. also one brand of primer and what appears to be a different brand of paint. There are so many possibilities that we could go on guessing for ever.I just hope it reaches a satisfactory conclusion.

It could be one of several things...I hopr that the painter makes good on the refinishing which it will require. I had an incident a few years ago when I was restoring a 1940's Dr Pepper refrigerated chest and was having interior tank liner pieces powdercoated.. the jobber tried three separate times and each time the powdercoat was bubbled by outgassing from the aluminum. SIXTY YEAR OLD aluminum. He had never heard of such a thing but eventually the third attempt was successful.

Yea guys, I'm sure it will get worked out in the end.
Speaking of "outgassing problems" during powder coating. I had the same problem. I have three Rochester two barrel (2GC) carbs on my 350 Chevy engine. Since they were all sourced from swap meets over several years they all had a different look to the metal finish. So I had the carb parts powder coated in gloss black. "Two and one half" of the three carbs came out perfect, but the top casting of one bubbled badly. They said it was due to the outgassing from inside the metal as it baked in the oven. They had to chemically strip it with remover, bake it in the oven to remove the gassing from the metal, then spray it black, then bake it. It looks just fine five years later.
Moral of the story, if it was easy, anyone could do it!

Now this is a scary post for me because I'm currently in the middle of exhausting, muscle cramping, tedious paint removal and now I hear that even with great prep bubbles may appear? The only bubbles I want to see are in my champagne. Oy.

Two months after having my trailer painted, I noticed tiny bubbles in the paint - about a million of them. I plan to contact the painter tomorrow, but I'd like your opinions on what the problem may be. The guy primarily paints cars, so I'm not sure if he will be able to figure out what the issue was and I hate to have it happen again. The bubbles are primarily on the top portion that is white. Anyone? I also posted this on Tin Can Tourists, so if you saw it there, just ignore
