micro blisters from the recent freeze

[steveo3002]

weve got a older run around that sat out in the recent snow and ice , seems to have very small micro blisters over the roof now

looks almost like overspray

its well looked after original paint , pretty sure it was fine in october , never known anything like that to happen on original paint ,just wondered if anyone else has had any probs from the cold...or ideas why its happened

are you sure its not tree sap or something like that, get some t cut or similar and try a small area

If it is microblisters they may go away when it drys out, usually return though.
Its moisture that has been trapped when painted usually, covering a vehicle up when its damp can do it as well.

hmm yeah i was sort of hoping they might settle once things warm up

thing is its original paint , cant imagine any trapped dampness wouldve stayed put all these years and then pop up now

never covered ..just sat with ice on it

doesnt really look like sap , im going to leave it until the warmer weather until i tackle it

Try cleaning it with a clay bar and then wax. it is most likely contamination of the paint and not micro blistering if it is original factory paint.

A couple of years ago I left my favourite Renault in a very very damp area and went on holiday. A couple of weeks later it had microblistering. That was in cellulose paint. You could pop the blisters and see the water come out.

I found if the car was left in the sunshine to dry out the microblistering disappeared. A (regular) wax polish would stop the blistering from coming back. (I also found that pressure washing is a bad thing to do when you have microblisters - it blows them off leaving primer).

Unfortunately a wax won't stop them coming back once they are there.

Difficult to answer that other than to say it worked for me Wax limited the things so they weren't a worry. There was evidence remaining but no big bubbles full of water.

The only cure is to repaint, Sorry.
