i would do a few coats of clear on top

Phil, I added a few layers of clear coat to the wood gun as an extra seal/protection, but didn't really think it would that beneficial to add to the aluminum gun. The way it was painted, any area that needs touching up, can easily be touched up with a can of spray paint...
Belizeman, I used can of Rustoleum spray paint. there are only $3 and change a piece, and allow you to cover quite a large area...
Judah, I first put down a solid base, then add some accent areas, and then add the splatter effect to blend everything more by not fully depressing the nozzle, this lets the paint sort of sputter out. Messy but effective.
