I have a wooden bed frame that was previously stained and (I believe) had some sort of clear coat, that I'm repainting with Behr Premium Satin spray paint + primer. After sanding with 220 grit, blowing off the dust, wiping-down with a dry cotton towel, then spray painting, most of the pieces turned out great. However, two pieces of the bed frame keep getting a crinkly finish as the paint dries. I've googled this, but none of the suggestions I've found (paint applied too thick, paint or piece either too hot or too cold, surface is wet / greasy / dirty) seem to be what's happening here.
What I've tried to correct the crinkly paint so far: let the crinkly paint cure for 2 days; sand-down the crinkly patches and surrounding area (I've also tried sanding-down the entire board); blow-off the dust with compressed air; wipe down the pieces with a damp cotton rag, folding / swapping rags to use a fresh bit until it comes up clean; allow the surface to air dry; re-paint.
In my latest attempt, in addition to repeating the above, I moved both the paint and the two pieces indoors for 24 hours to warm up (68° F). Then I used a fresh cotton rag to wipe them down with 70% rubbing alcohol, allowed them to dry, then repainted, but it still turned out crinkly.
Any advice would be appreciated!

The only times I've ended up with the crinkles is if I added a coat more than 2 hours after first coat. This happened because first coats were skinned over but wet under.
That may or may not be your problem, but you might try sanding it back down -- and seal it with poly first -- let dry for 2 days -- then paint lightly as if you're painting sheet metal. This needs much less paint than going straight to wood. This has worked nicely for me lately
