need a paint pro for a simple question. Options

alright so i need someone who does paint and body work for a living, i need a straight answer and not opinions.

anyways i just got done painting my front end(well most of it) and i put my bumper on but it was such a pain to put on now, its like it shrunk a tiny bit or something, now note i did not paint the bumper on the car i removed it and just set it up on two lawn chairs. for paint i did lacquer on top of mostly factory paint(good bit of it was removed from prep work) but nothing else was different, the shrinkage was not too bad but now my bumper to hood gap is not correct. so what i did was get it close and going to let it sit for a few days to maybe let the heat get it back to its original shape. theres no warping going on or anything, and fit perfect before i painted it so im thinking it has to do with the paint or just from the temp outside combined with how i had it propped up for painting? thanks in advance .
