I'm Finding My Feet Here Now
Unfortionatly it's a case of getting back down to the problem,repaint!
Solvent pop has many causes- too fast paint thinner,to fast hardener, not long enough flash off times between coats, baking to early, too heavy coats.

Are you asking about solvent pop or microblisters? Solvent pop happens pretty much when it's painted and baked, as the name implies the solvent is forces its way to the surface whne the heat is applied. Micro-blisters are caused by moisture that has been trapped between layers so has been painted over, they can show up a number of years after the car has been painted, usually in cold weather when the water freezes and expands. I have a car at the moment that was painted about 4 years ago and has been fine but the recent snow has caused micro-blisters all over it.

Can also be caused by dirty water being used in washing down areas after wet and drying.
I had a car with this all over, a mini ended up in court and he paid someone else to do it, had to take to court again to get money out of him even after judgement!!
The dirt decays and gives off gas which lifts the paint in blisters.

I cant tell you what causes it as i never got to the bottom of it on my old mk2 granny but the fella that painted it for me reckoned it was a reaction to the old cellulose(sp?) paint allready on the car 
Mine started off with a few small blistery bubbles on the bonnet and wings and i was told the only way to stop it was to go back to bare metal. The problem was after being in the oven having the front painted again, other problems appeared like micro blisters and cracking on other previously unaffected parts of the car.
fucking soul destroying when you spend so much time and money on something and this kind of shit happens.

Solvent popping is usually caused by painting on top of a layer of basecoat before it has properly flashed off or 'cured'. When you buy paint you can usually find a technical data sheet on the manufacturers website which gives you recommended flash off times under various atmospheric conditions i.e. in an oven/room temperature. If you don't follow these and apply another layer the solvents from the first layer haven't had time to disperse and force their way through the top layer of paint, causing the holes you've described. It's pretty nasty and unfortunately the only way to solve it is to do it again.

Thanks for the feedback guys, the areas where it's happening are on the tailgate and bonnet I spoke to a painter who is on here often, he believes it's down to the primer which I honestly believe is true due to the shell and kit including bonnet and tailgate were painted separate! And there is no sign of blistering on the shell, in any case am still not happy you pay money fir a job done properly and get shit! Hope people learn fome this and get proper tradesmen/ good companies who will redo the work or refund your money!!!!!

'The main reason I started Blue Oval is my love of Fords and I also wanted to be able to offer a great service at good rates.
The best way of ensuring this is to have enthusiasts work on the cars, who will always do the best job possible as they have pride in their work, know what they would expect for their own cars and take the same care with customer's cars.
No corners are cut because most of the cars we work on are show cars and are therefore scrutinised by other enthusiasts. Any mistakes, or cut corners, result in a bad name and it's my intention to have people talk about Blue Oval because the work is always top notch, completed to an excellent standard and at a good rate.
I take great pride in seeing my work on show and the cars once again looking their best.'
Trading standards should have a read of that!!!! Hahaha.

The place that sprayed my Sapphire Cosworth did no wet flatting at all, everything apart from the final flat and polish was done dry as they claimed wet flatting could cause micro blisters in the oven due to the porosity of the primer.
