Just a quick update. I have all the clear coats sprayed. I've been very happy with the way the EmTech water based lavquer lays down...just beautifil. It sprays like nitro, flows out smoothly, and cures very quickly. Of course, I've added a bit of help in the curing dept.
I hang the guitars in my studio closet and I've placed a small space heater ( no extention cords involved...keeping it safe) in there with them...it keeps the room at about 100 degrees F. That coupled with the dry air indoors from the A/C really help the spraying schedule.
I spray 2 double coats, place them in the hot room for an hour, spray 2 more and so on. It's been great. And when they come out of the room for another few coats, they're quite warm and the coats flash very quickly...allowing the double coat process to go very quick without fear of sags or runs.
This will also allow me to speed up the cure time...normally fully cured in 100 hours. I used this hot room on my $210 Challenge entry and buffed it out the next day...only 20 hours after the final coats were sprayed.
Now I just need to wait a few days for "baking" and they will all be ready for buffing.
