help paint problems
my car has been painted for about two months now. I went to look at in the shop tonight and there are some very fine looking blisters in the paint 
it seems to only be on the vert hatch. this is the only part that has been color sanded and buffed. the car was stripped with a razor, no chemicals. primed several times with 2K high build primer, blocked out then sealed with epoxy sealer and painted with a tri coat red. all materials are Martin Senour. is this solvent poping? you realy can't feel the little blisters. it looks lilke when you would get water in your air line. just a bunch of small blisters. this is not good

Definately sounds like solvent popping. Probably occured after car was exposed to hot direct sunlight and the heat activated some of the solvents that had not cured fully. That would explain why it has only happened on the deck lid (more exposed to direct sunlight). Have you checked your hood closely?
Fish eye would reveal itself immediately due to the contaminates on the surface.

sounds like contaimination while spraying - moisture of something else in the lines as previously mentioned.
Most of the time solvent popping is from residue chemical strippers from improper or incomplete cleaning and neutralizing but since your car wasn't chemical stripped that wouldn't be an issue.
Any chance moisture got into the bare fiberglass before priming and sealing? that would do it also as the moisure is trying to work it's way out.

This is solvent poping. THere is not alot of cures for this. You may try sanding the paint with 1500 and cutting the surface open then let it out in the sun for some time. Chances are the damage is done.
good luck

I talked to my painter today and it sounds like it may be in the primer that I sprayed at my shop. I did have a water trap and a filter at the gun but I was getting a few fish eyes in the 2K primer. if this is the case it really sucks because the only cure would be to get all the primer off the car. luckily only the back half and the jambs are painted. but still this was close to $900.00 in paint and materials. that would also mean it will have to be re primed and blocked out again. basicly starting from scratch again. the car was never in the sunlight it has been in my shop ever since it was painted, also the bare glass never got wet. I think fish eyes when I primed it is my clue.

Solvent popping is caused by using a reducer that is too fast. The top of the clear will skim over, but underneath is still wet. As the solvent evaporates, it can't get out of the clear because of the surface has skimmed over. So it forms a bubble within the still wet inner clear. This has happened to me when using heat or lights to speed up the drying/curing process.
If it is solvent popping, you will have to remove the clear and base/clear the area. Solvent popping can be caused by the primer if you immediately paint after applying primer. It is normally recommended to wait overnight before painting over primer. Sometimes primer will shrink overnight as the last little bit of solvent evaporates.
