Here is an interesting spin ..I phone there technical support, which recommend I read the "manufacture" instructions.
Here is what I found just added..I know this because I NEVER saw this posted before! I will give it a shot again as test run. I bet I violated the WFT the reason its not drying.
Finish Coats: Fiberglass, Aluminum & Steel: Professionally applied spray coat applications yield superior results, however Revolution levels exceptionally well in brush and roll applications. Unless you are experienced with spray equipment the best way for the do it yourselfer is to apply Revolution is by roller coat. When properly thinned in appropriate temperatures (SM-101 Thinner 15%-25%) Revolution levels exceptionally well. It had a good defoamer “bubble popping additive” so the need for tipping is eliminated. Aside from spraying, which offers the best film thickness control, rolling is often the best way to achieve the recommended wet film thickness, 2 mils WFT (Wet Film Thickness). The recommended DFT is 3.4 mils. Applications applied too thickly may not adhere or level properly, run, sag and take days, or even weeks to cure. Always adhere to the manufacturers recommended WFT and DFT (Dry Film Thickness)!
Revolution must always be stirred or shaken thoroughly before use. It may be brushed, rolled or sprayed utilizing conventional and HVLP spray equipment. The solid content is exceptionally high so thinning will be necessary in most applications. The amount of thinner required will vary depending on ambient temperature, type of equipment used, method of application, humidity, color and amount of control desired and tip size in spray applications. We suggest beginning with minimum dilution at first and increasing dilution as needed subject to your individual application requirements.
Revolution may be built up to achieve a higher DFT where desired. Two, three or more thin coats are acceptable to achieve the recommended DFT. Boot and bottom stripes should always be applied over top of the recommended DFT. For best results recoat within 24-48 hours or sand between applications. Allow top coat film to cure thoroughly before allowing it to enter full service duty. The recommended minimum cure time is 7 days under most conditions. DO NOT allow newly applied paint to get wet for a minimum of 48 hours. The dry cured film may be wet sanded and buffed to remove runs and blemishes.
