I have done around 10 to 15 AR's as well as shotguns, some my own, some not.
I take the guns apart, and the prep consists of acetone, several wipe downs, then let it sit overnight.
I only do these in the summer time, so I can hang the painted parts in the sun.
I use Fusion plastic/metal/ wood paint that will dry fast, around 20 minutes per coat.
I apply two too three base coats, then let it dry overnight.
Next day, I apply one or two cross coats I call them in a contrasting paint to the base coat, then again, dry overnight.
The third day is when I do the camo patterns, depending on what the customer/owner wants.
The last paint I apply is two seal coats, then put the thing under a heat lamp for three days, then take 00 steel wool and buff off the shine.
I just got into PCP guns and have a very nice Brocock Sniper Magnum in .22 caliber and will do the above paint job to the gun or I will have the barrel shroud and stock cerakoted.
