It lasted a lot longer than I expected - I generally ran out of gel in the jar long before it began to affect spray-ability. I guess it depends on temperature and how much hardner you mix in.

I think you could theoretically clean them out for reuse. But at $5 each, its hardly worth the labor.

Each coat had to cure overnight before sanding. In my case 3 coats = 3 preval sprayers.
