I went to give my car a rinse off and wash as its been in storage on and off for almost 2 years - I hardly brought it out this year because the weather has been that poor.
Anyway I notched a few marks on the front end, a small patch on the bonnet and on the tops of both wings.
It looks like water under the paint/lacquer but don't really want to pop one to find out.
Each mark is probably no more than a mm across but there's a few. There are no other marks anywhere on the car just either wing and both edges of the bonnet.
The car was fully painted 8/9 years ago and was a flawless job so can't see it being anything to do with that but clearly something has happened in the last year.
I was thinking as it is clear over base, would I get away with flatting the lacquer off until its down to the base then re-lacquering or is it a total DA then repaint?

It sounds very much like micro blistering that its suffering from. Is the car steel or fibreglass? Can you post a couple of pics please?

Thanks
Ill see if I can get some photos over the weekend.
The car is steel but there's no chance of it being the start of rust purely because of where the 'rash' is.

we have a old 911 in with us now thats covered in prefect round bubbles , the car sat for many years with car cover on (helping it to sweat), its going to be a full repaint.

the 2 original panels are fine all the other panels that had been repainted are effected all thou the paint and colour match are great.

We also have an supercharged Aston Martin in too which again has sat for 5 years in for repaint and restoration of wheels and complete interior.

this too has bubbling on the front wings which have grown in the cold damp weather (plastic wings).

witnessed lately (came in for service) a 512TR which had perfect paint (we detailed it a few years ago and removed the engine for complete service) this now has the same bubbles on 2 panels after its spent many of the last few months standing outside (in the shade all day) , this too will be repainted soon wink

constant cold damp conditions and lack of use dont do the cars any favours.

this year seems to be very good a growing the dreaded water bubbles , normally i would only see this on cars like lotus / noble / tvr etc and happens when the temps drop to freezing or more for many days.

This will be due to moisture trapped in the paint which then freezes and expands.

The reason for the delay is due to paint is more soft "flexible" when its new and young and is still "gassing" "breathing" this over time changes, and the paint becomes harder and less flexible and forgiving till in the end it fails , if by cracking , blistering etc

Never flat clear over base back down to the colour, it will sheer the pigment, you always have to repaint in that case.

Would you say that this is because most products are developed & tested in warmer and less damp climates than ours?
