I use POR all the time. I usually spray mine and I reduce it with POR solvent. It sprays out really nice. I also reccommend top coating it with POR chassis coat. It is a nice semi gloss black similar to factory finish and is UV safe. This stuff dries with the water out of the air so depending on where you live and the humidity affects the way I dries. If you are in a dry climate or inside a heated shop I would wet the floor down after you are done painting and I will speed up the drying. Do wear gloves or you will wear POR for a couple weeks.
