Somewhere I heard that BPS paint from Tractor Supply was a great paint for tractor an engine use. It is very reasonably priced. I have used automotive enamels for many years with excellent results, but just couldn't resist trying BPS paint today on a small antique lawn tractor project. I should have known better when I read that it takes 4-6 hours before it is tack free. Sounds like Rustoleum to me. They aren't kidding. I sprayed under ideal conditions of temp and humidity and used the recommended thinner. It took 6 hours before I could move the pieces and I wouldn't exactly say it was tack free then. Every bug within 50 yards had a chance to visit my paint job. More than a few stuck around. One hardy bug managed to crawl over 7" in a crazy maze pattern before he finally gave it up. It says wait 24 hours before recoating, but my experience with other enamels makes me a little leary of that advise. I will try recoating carefully. I definitely have to recoat, if for no other reason than to make all the bugs the same color. At the same time I can sprayed Duplicolor auto enamel on the tractor seat. 4 coats and no bugs had a chance to stick to it. I don't have a spray booth so I have to use the warm summer weather to do my larger paint jobs. The auto enamels skin over very quickly and are tack free in an hour or so. BPS may be the best paint sold, but I can't afford to use it. I will stick with the quicker drying auto enamels even if it costs 10x the price.
