I find that warm parts coat very well with por15 and I usually clean the top of the can then cover it with a platic wrapwith a rubber band around rim.
i can get a few weeks before it gets enough air to form a skin on top of the paint.
also,wear gloves ,especially if you are going go to work after using.
I painted my frame a few years ago with POR15 and am happy with the results,as it sat outside for 2 years while I struggled with the cab.
