You know what's a good, cheap paint sealant? Aqua Net. No joke. Probably not quite as good on something like a handle that will get sweaty from being held all the time, but for the rest that you handle less often, it'll work fine. I usually spray several coats of Aqua Net on all my painting accessories. ^^ For something like the handle of our struggle bats, though, I used an actual, more water-resistant sealant. : P
