I'm going to hopefully modify my 3pi theater series speakers to include 2 12" woofers, and since my speakers are just bare MDF right now, I might as well finish them to make them look at least a bit respectable. I want them to be able to play outdoors (not in the rain or anything) if needed, so I figure veneer or other paints might not be a good choice. We finished one of my friend's subwoofers with the spray can truckbed liner and it looks ok, but not spectacular. Im wondering which brand you guys would reccomend? Also, what sanding techniques do you do after you have sprayed a few coats of it on? Finally, what kind of primer do you use on the bare MDF first? Ive got some generic wood primer in the garage and was wondering if it would work. Thanks!
