Doing a guitar body, I had no problems with color coats, and the first clear coat went on beautifully (same brand rattle can). The 2nd clear coat crazed like it was wrinkle-finish paint. It didn't harm the color coats, and I ended up carefully wetsanding and buffing the clear off and just rubbed out the color coat.
The same brand clear on the bare maple neck... 2 coats didn't craze, but it also never fully cured. Ended up stripping it (which was a PITA because it just balled up in the paper like rubber cement) and using a thinned brushed on acrylic.

the problem your having is because of the thinner content in the clearcoat
it causes the dryed clear to react
as for it not drying at all on the other piece there must have been some other clear underneath which was a 2k or something
im a pro painter so if ya have any questions just ask
