Hey everyone, I bought my dream car in the summer last year and even built her a pop up garage to try and prevent any damage over the winter. I looked today and it seems like there are small bubbles all over the car 
I’m very worried the garage is causing more harm than good. Any advice on how to proceed?
What pop-up garage are you using? Do you have a picture?
Is a clarke garage from machine mart. Thought it would be better than a cover as it wouldn’t trap the moisture so much…
I have seen bubbling on my nc that i had it fixed. it can happen with newly applied paint, and you don’t wait until it cures completely before applying a second layer. The paint release voc and the layer above bubbles up. It can also happen more often on painted composite materials over time - as it was in my case
I do wonder however whether its some Chinese job with whoknows what materials chemical composition, rain dropped onto the car and caused a reaction. Dunno but definitely weird
I do wonder whether the car was recently sprayed. If it was I reckon thats the cause
Yes, the guy I bought it from had a body shop, think he painted it last year…
It’s been fine for months though, and I’m in Scotland so it’s seen some rain! Only today I noticed it after being in the garage for 3 weeks…
my best guess is that he did a poor job painting it…
Okay so maybe an underlying issue and it’s still best to keep maz in the garage?
Make sure its vented so moisture can escape I don’t really see an issue using with it tbh. Pehaps leave the front “door” not zipped all the way down
Does look like a paint issue, not correctly applied/prepped.
Do keep your pop up garage ventilated though, at least to avoid moisture build up on the inside, although these types of structures should have plenty of air circulation.
Think this is a sign of silicone contamination. The only solution is for the car to be repainted. I’m guessing its M8 Montego Blue? Hard to panel match.
Been there.
Very much doubt it’s the pop up…it’s got plenty of venting going on.
That’s contamination of some airborne odourless & colourless stuff like silicon or some such,
Nothing but removal of paint & subsurface undercoats will cure it.
It needs to go back first to the workshop for a chat…but I’d not hold my breath.
My issue was bad luck. There is a coffin building business next door to what was my spray booth shop,
Guess what they use to ease the click joints of cheap coffins with? The wind was going in the wrong direction that day.
PS:
Is that oil dripping onto your gravel in the pop-up?
Looks like the panels were not prepared properly prior to painting. Only solution is to strip it right back & start again. Probably more work than the original job!
Another remote possibility is frost damage.
I came across this in the distant past with water based paints on metal substrate (film equipment and not a car), but only if the water-based pigment colour and legend layer was not 100% dried and cured before sealing with a more conventional solvent based clear lacquer abrasion-resist layer.
All is OK until either a boiing hot heat from direct sun, OR a heavy frost. Tropical sun=steam, arctic/mountain frost = ice, both expanding the trapped hints of moisture enough to blister the paint.
This sort of blustering normally happens a lot more often with composite panels (eg PRHT deck and roof, boats, etc), but usually only if they have not been correctly dried before primer-sealing AND again after water-based painting and before the final sealing.
I agree with the others above; cut right back, deep de-contaminate, and correct respray is probably the only answer.
Ok thanks, so do you think it’ll get any worse or can I hold off on respraying it until I’ve got a bit more spare cash?
It’s the Dakar model so a lovely twilight blue 
Hmm I mean it may have had 1 or 2 days in the frost back in November but didn’t notice it back then!
Ok thanks for your help 
The guy I bought it from was who painted it last… do you think it’s worth trying to ask for a repaint? 
unlikely!
It’s blistering caused by moisture under the paint, as the earlier post says its probably down to poor prep prior to a respray.
I had it on a few panels on an old Mk2.
The blisters do go down when the weather warms up but won’t disappear completely.
Only solution is to get the panel rubbed down and resprayed properly.
I would certainly ask him about it.
Be polite and understanding to begin with, after all, mistakes can happen.
He might feel a twinge of conscience or even professional contrition and simply offer to sort it for you.
