Paint Help Please

Ok here's what I have done all bodywork n stuff then sprayed with Autobody Master High Build Urethane Primer blocked it wet w/600 then sprayed with Matrix Base and Clear. there was one spot on the edge of the hood that masking got over and didn't notice it. I blocked it down c/paint/primer to edge it back down. shot a coat of same primer over it. Wet sanded with 600 then 1000 throughout the surrounding area to blend in. shot the paint and it just cracks up around where the primer meets the paint. Any help appreciated Also the shop is heated therms on bolth sides of the card stay 68-70 I got reducer/cat Med 65-75

IS IT CRACKING OR LIFTING???

It seems to be more lifting (then ovcoarse cracking out from the lift)

Are you waiting long enough between coats?

ok what did you sand it back with as in grit of paper i thank if you did not use a grit like 320 under the primer it is lift up because the prime is not stiking to the new paint and the redurce is gonig all the way thuogh causeing the paint /primer to left try using you base coat with just half the recomend reduction

I believe my problem was not letting it flash long enough/possibly to heavy of coats I sanded it back down and the orig paint I sprayed didn't seem to be fully cured I sanded it back to a point in the paint that lopoked cured and I am going to let it sit in the shop till thurs then check and seef if it lift w/ lil laquer on a rag before I respray I think thatll work ???

dont put laquer thinner on anything that is primed. primer is designed to absorb in an effort to draw paint to it. if you want to see if the primer is lifting i would suggest just looking at it. if youre going to let it sit till thursday you will know just by looking at it if it has lifted or not. good luck

thank I will pass that step then
