We use a silicon based latex paint. The stuff is extremely expensive, but it works like a champ! We brush it on and you would really never know it - looks just like it was sprayed on. It is a thick piant. Areas where you stop and painting at and let it dry, I would bet that it is almost nearing 1/8" thick. If we get lucky like we did this year, it is better if you can let the equipment set up for about a week before taking it back out for either use or simply to set in the weather. We do all of our trailers in the same stuff each winter, as well as the flatbed on one of our trucks. It's good stuff though.
