    Default Solvent pop

    I donít have pictures but a friend of mine had a 32 car restored at what is suppose to ba a reputable shop. Some of the panels were done 2013 & some in 2019, now the paint is reacting looks like a very course sponge or solvent pop, this is occurring on panels that were painted at both times. Right now the problem is in the radiator cover, hood, both doors and 3 fenders. The base was prepped with acid etch primer. My opinion and I am a week end painter but if it was mine I would go to bare mental. But I put it the experts , I know it is hard without pictures , the shop claims it was caused by the owner, this car has not seen bad weather since painted, always garaged.
    Thanks

    It all depends on how much labor you want to spend on it and how well you want it to come out. Personally I'd recommend taking it down to the metal then shooting one or two coats of epoxy primer before painting. If there is any body filler under the existing coating you'll probably want to make sure it's leveled properly using a filler primer.

    sounds like the shop is looking for excuses. i would ask them what they think the owner did to cause it.

    I thought solvent pop happened when the last coat skimmed over and solvent was trapped, not a job that was out the door in 2013 and 2019. I might be wrong but the time line is off for solvent pop. Best of luck to you.

    I was thinking the same thing. There isn't anything I can think of that would be caused by the owner who had nothing to do actually painting the car.

    Sounds like the normal paint rep trying to lay blame (only the paint shop itself in this case).

    a picture might tell more, but lousy prep work, contaminated air lines, or incompatible products seem like the only explanation. the only way to be sure the new paint will be good is to strip to metal. then you know exactly what you have, and can stick to a known good product line. people always balk at the cost of good paint, but it sure beats doing the job twice, or three times.

    You would have to know how the original body was sanded, filled, prepped and painted to know the cause. For instance the "sponge" look may be rust that was not properly addressed at the time. Leaving ANY amount of rust unmitigated will absolutely come back to haunt you. You may be correct when speaking of the acid etch primer as the culprit, this is the reason I don't use them. Product compatability when using etching products has to be closely monitored. Etching products absolutely have their uses in auto restoration, I just don't use them in terms of body paint layering application as there are numerous products that work just as well, if not better, without all the fuss.

    Go with Lens advice and take it to metal. This is but one of the instances I am always saying "don't short cut". It makes no sense to me to put in all the labor, time and money just to have it fail down the road. On this site you will see numerous occasions where painters speak of "down the road problems", and now this is where your friend is, sad for him.

    This is not your friends fault, it is the shops failure. Ask your friend if any other car he has in the garage experienced the same problem...doubtful

    Thanks guys, appreciate your help. I was wondering if the acid etch primer had anything to do with the problem.

    Probably never know but it will have to be striped.

    added more pictures, painted cowl after first done, other pictures show the problem, could old hardener cause this problem a couple of years after painting?
    Thanks

    i don't use old hardener on anything i care about so i couldn't say. i've not had it be a problem on the less important things i've used it on though. but if it's been opened for more than a couple of months without any gas to protect it i'd toss it. if i protect it with gas it lasts a whole lot longer. usually if the paint hardens, it's good. it's what's underneath that comes back to bite you. (usually)
    thanks for uploading the pictures.
    it looks like the something is shrinking as it ages. very strange. do you know the exact products that were used on it?

    The last picture appears to be a bad case of orange peel which may be able to be sanded and polished to a smoother finish.

    len has a point about the orange peel. i was assuming you didn't think it looked like this when it was received from the shop. if it did indeed have the orange peel as delivered then sanding and polishing is the corrective action and should have been done before delivery.
    can you shed some light on this?
