That POR15 is good stuff and is about bulletproof, but it sets up and skims fast, as mentioned above. Never have tried to spray it, and I'm sure it is nasty to your health. I have top coated it in areas that showed, with Rustoleum or similar spray cans, and it looked good. I had about a half quart left, carefully put plastic wrap over the top and reinstalled the carefully cleaned lid. A few
months later I opened the can to find a wonderful petrified hockey puck. An EXPENSIVE hockey puck!
