Did not like being rolled on, did not try to spray as its rather nasty stuff chemically and aerosolizing it seemed like something you do when you must vs to the bottom of a service body as part of a bed swap.Brushing worked the best.Should have read a little more before purchase, because the aluminum version is not just color or metallic paint but literally contains 2Lb of aluminum powder per gallon, which helps fill small pits etc. and would have been my base coat on the top side of the bed. I’ve ordered some to use as the base coat for the frame of the truck the service body will sit on, but know I will have to brush it on or use a large orifice in my sprayer because of the Aluminum powder.I am very satisfied with the gloss black. It’s almost ceramic hard once it’s dry, but you have to use a brush and have to keep the applied material in very thin coats. Globbing this stuff on will only cause micro bubbles as it cures which can allow air and moisture in and they don’t sand out well. I used 3 coats and then top coated because I got some runs and globs in a few corners and behind hangers, etc. I figure that if 2 coats in minimum then 3 is better and will fill in any little micro bubbles and while I used as an undercoating to my service body, a top coat of gloss black oil base enamel couldn’t hurt.You won’t need any thinner unless you want to spray it and you must use xylene or their brand of thinner not lawyer or paint thinner. Also a RESPIRATOR!!!!! This will not give you cancer if you expose yourself to a toxic amount of vapors. It will kill you or give you brain damage rather quickly. Paint with brush in well ventilated area (outside with a breeze) or use a damn respirator. NOT A DUST MASK, Must be respirator good for organic vapor.Once you’ve opened your can and are done for the day, putting a light float of xylene in the can before you close it will keep it from skinning over and you just mix in before you use next time. Do not mix in immediately or you defeat the purpose of the float. Also use plastic wrap/bag/something between the paint can lid and paint can if you spliiled any in the little groove of the can. It will weld lid to can otherwise.This stuff does not sand easily. It does scuff easily for multiple coats, but you won’t want to try to feather it or bring back to bare metal once cured. TRUST ME ON THIS.
