Thoughts on how this happened?

[jct]

Car was painted back in april waited about 30 days for it to cure then i put my car cover on it while i did my engine work. And last sunday i took my cover off and spotted the paint bumps along the top rear quarters of the trunk. It will be going back to my body guy in some time in October, for this paint correction and other work.

Did my car cover do this?

Perhaps still present solvents were released and trapped under the cover?

Usually, paint bubbling is caused by a reaction between the paint and the primer applied under it or because the surface to which the paint was applied was "dirty" with wax residue etc.. It can also be caused by pigment that has been over sprayed by clear coat before the pigment layer was fully cured. In any case, you are looking at stripping and repainting of the effected areas to repair this defect. I feel your pain.

I shouldn't comment about a paint job via a picture on the net by who knows what kind of camera or resolution, but I've seen tons of photos of net car images in just the past 5 years and with the advent of pretty good phone cameras I would safely say your got a lousy paint job there. Is there really that much orange peel before your eyes in the first (top) photo?

Agreed. Maybe give the car a wet sanding and a fluff & buff might fix it? Good Luck

From what I can see at the angles you've provided looks like contamination/solvent in the primer.

Can't tell anything from a picture. Need to see on top of what layer the bubbles are lifting from. Something contaminated it. Maybe moisture in the air lines or something not cleaned off the surface. Hope it stays confined to that one area.

i used the potato camera on my phone to take the pics crummy pics i know, i'll get some better photos this weekend :-\

That appears to be either water or solvent popping through. The cover may have caused the popping or at least contributed. The types of cover and paint would make a difference. Single-stage enamel, covered with a plastic cover would probably pop pretty quick after only 30 days.

the cover i am using is the ironshield car cover

It’s plastic. Even though it breathes through vents in the top, it could definitely cause localized solvent pop because it could randomly trap any breathing that the paint may still need to do. I’d wait at least six months before using it on fresh paint.

should i use my cheaper autozone car cover for the fresh paint then, after it gets fixed?

I would leave it uncovered for the first 3 months, If you have it someplace where you have to keep it covered, go with a cloth cover, not plastic so the finish can breathe. Car covers aside, it looks to me like a poor prep job on the part of who ever painted it.

it was around a 3500 paint job...

well at least i know it's my f-up oh well live and learn

I would be headed back there ASAP for an explanation as to what appears to be shoddy workmanship. Unfortunately, expensive work does not always translate into quality work. Was this a single stage or clear coat?

My body/paint guy told me to never put a car cover on a fresh paint job for at least the first 3 months as the solvents need to slowly release. And you should not expect $3500 to pay for a quality paint job. It means the paint quality and related materials were poor and/or the guy couldn't spend much time on the prep or anything else and still make any profit. With paint and body work, you get what you pay for.

For the average car needing mimal body work, anything less than a $10 - 12K bill won't cut it for long term good results. And the painter will need to keep the car for a about a month to let the various stages dry between coats for good results. Then after letting the car dry for another 3 months after completion, then the color sanding and buffing can start. Good results can't be rushed.

with a clear coat

 

[moper]

That's from solvent being trapped in the heavier sprayed areas of earlier coats working it's way out. Because there was not enough flash time between the coats. I made that mistake once. It happens. The only fix is to sand (wet sand if there's enough color there) and reapply either base then clear, or just clear. That ain't gonna "just buff out".

 

[jct]

i'm not gonna worry too much about it, at this currant time it will get fixed when i take my car back to my body guy to fix holes in the floor i'll be taking it to him some time in october and he'll most likely get to it in a few months or less
