paint reacted to something ?

I sprayed my car yesterday with the SPI dark red paint. I thought I had the car prepped well but have two small areas where the paint wrinkled on the hood and trunk. I have no idea what caused that to happen.I wiped the car down with medal prep I had that was quite old but I thought it should still work. My question is should I strip the spots to the medal or give the spots a few days to dry and shoot sealer or primer on the spots to smooth them out ? Also it will take a few days so should I sand the bc and what grit before I try to put the cc on ? Thanks for any ideas how to fix this problem.
 
I'm kinda lost on what you had done prior to spraying paint. How did you prep it? It kinda sounds like you used metal prep on raw steel then painted, is that correct? Any area that had prep work and was cut thru should have been at least sealed with either 2k then sanded or Epoxy with no raw metal showing anywhere.
Please explain what you had all done before the paint was applied and that should shed some light as to where the problem lies
 
I sanded to bare medal, sprayed epoxy primer , waited a day and sprayed 2k primer. Block sanded with 400 grit . Other parts of the car look fine , just 3 to 4 inch area on hood and trunk area that for some reason is soft and does not seem to want to dry. The spots have a sticky feel when I run my finger over it . Would that be where I got the paint on two heave and did not give first coat enought flash time ?
 
Nothing really to do with flash time, those two spots have a real issue of some-sort and it most likely coming from the metal.
Slowly wet-sand down and see where problem stops, that will be the answer.
Common causes of this is:
Acid film
Cleaning with lacquer thinner
UN-Neutralized paint stripper.
2K primer mixed in gun cup and small part did not get mixed with iso's.
