Finally got back to this guitar after a 5 month break. Lot of problems with paint finish getting dents etc. Anyway today I started on clearcoats. Decided to use spray can nitro - as found poly finish I applied to last build was still soft after 6 months and kept damaging - so thought I'd try nitro again and go for a thinner overall finish this time. Applied first 3 coats (first was a dusting) at 1 hour intervals. 6 hours later - it has already major cracking ... long cracks 15cm+ !
Some around screw holes.
What would folks recommend ?
I would normally be doing a light sand before next nitro coats in a few days .
Will the subsequent coats melt the nitro and fix the cracks ? Or will they still remain. Shoukd I even fine sand yet ?
Didn't have issue like this previously.
I sprayed late afternoon and left guitar outside in evening ( possibly 8 degree temp change thinking about it)
Build has been a nightmare. I'll go back to poly and patience next build
