You may find they go right back to the metal, microblistering can also be caused by water or contaminants which can happen between the metal and primer or the primer and paint, thankfully its not the dreaded rust! (well shouldnt be) and as above is the way to fix it 

 

I'm with Alex on this, micro blistering caused by water in the paint or primer. The only thing with this is to sand it right back to bare metal.

The reason here is if it is the primer then rust will form on the metal.

 

myredmini suffered this very problem and so have i. Not good news i'm afraid.

That looks very much like micro blistering im afraid. In which case it won't polish out. Its underneath the paint.

where did you get the car from? been imported from the UK recently?

 

Bad painting equipment and technique has caused this and it has been exaggerated by the large change in climate.

 

Seen this many many times.

 

This will go right back to the metal so the only real solution is to rub it all off and start again.

If you do this yourself remember primer is NOT waterproof! Don't expose it to the elements until you have the topcoat on!

I dont think that humidity, looks more similar to silicone bubbles, maybe something wrong between coats its causing reaction.

Could the reaction have been caused by a fine spray of brake fluid? Same thing happened to me.

Definitely this, I've had it on a cam-cover I sprayed :cry:

 

contaminants, not necessarily water, between the layers of paint/primer

Mine was definitely water from an old compressor even with a oil/water trap. Not oil or silicone as I would have got fish eyes in the paint. A really good quality water and oil trap is the only way to go for a home respray. A bodyshop should have a decent system installed so should not be an issue.
