6.5" Grills in need of some!

Hey guys, well I just installed some new panels in my boat with 6.5" alpine components. Now they look awesome but they are very open to the elements the way the stock grills are. I was wondering if anyone knew of a place to purchase marine grills or just solid fine mesh black ones? ALso I think I remember a spray of some sort that you can spray onto the speaker to protect it? thanks

I know you can buy grills on ebay. They have many different ones, the easiest to fine are the white ones but those look kind of boring, I suppose you could paint them black.

Your speakers arent pioneer but heres 4 grills for cheap, the bad is they say pioneer but if you can live with that here ya go

I actually talked to a stereo guy looks like im gonna need to order another model alpine cover so they will sqrew on and hold to the speaker.

O how do yours attach? I know the ones on my pioneer 6.5's skrew on.
