Sorry for the heavily cropped images, only way I can 'resize' it.
Hi Joe, so long as you've used compatible paints the most likely cause of that is the coat underneath not being completely dry. Some paints take weeks and months to properly harden. It looks like the previous coat may have been a little thick there, so the top drys, but the underneath takes a lot longer as its difficult for it to outgass through the dry layer. When you spray over the top again the solvent seeps through and reactivates the paint.
I would leave it to get really really dry, then sand that back until the crazing disappears then re coat. Its annoying, but you just need to be patient.
It was enamel primer with enamel colour
The primer coat was thick everywhere
That may be the case, but in that spot it clearly wasn't completely dry. They only other explanation would be some kind of oil or solvent on the surface. I've called it crazing above, but I think the more accurate term for this reaction is wrinkling.
I did let it dry for a week, and the area where it has wrinkled was dry, no oil or grease or anything... oh well I'll just sand that little area and try again, if the problem persists than we have a big problem
Perhaps I laid on the paint too thick in that area, the guitar body does hang pretty low from my contraption I have built to hold necks, bodies etc. I have to get on my knees and duck down (I'm pretty tall) in order to spray properly on the bottom, and lack of lighting on the bottom of the guitar body makes it hard to see how much paint I've really sprayed.
Yeah I'd say thats the issue. Don't stress too much, it happens. The more drying time the better. I was leaving mine a week between rub backs and even then I wasn't totally convinced the top coats were hard when I went to cut and polish. Lots of thin well dried coats are always preferable to thick ones - even if it lays down without runs etc. That looks like it will patch OK.
