I use the liquid clear coat from Component Systems for my jigs. I paint the eyes on then after they dry, I dip in the clear and let it cure for a couple days.
And yes, a couple dots of flammable paint on 500 jigs will go Boom! Had a buddy that blew up his garage cause of this! I store the laquer paint I use for my eyes in the house during the winter, just got to keep it away from the kids and any flames.
