A. We spoke to paint specialists at Western Spray of Crediton, Devon. They advised that microblistering is always a result of moisture that was already present in the primer coat or undercoat, regardless of the material the car’s made of or the paint system used. It can remain sequestered within the primer for years without harm – but as soon as the right conditions come together, it’s forced out and causes blisters in the top coat. If you pop a fresh blister, you’ll find it’s damp inside.
Sadly, rectification will involve stripping the top coat off. In theory, if the old primer is exposed in this way and then dried off, it can be painted over safely."
I think that popping about 300-400 paint spots and then repainting them and flatting them down and polishing them will make the car look a lot worse than it is.
