you should be able to just use the resin...dry resin by itself is not that strong, but since its over MDF, its no big deal. You can just brush a coat or 2 on, let it dry well, and come back and sand it down later, prime, and paint...im about to start doin that on my friends box.

If you grab some polyurithane,, (sp) primer that stuff works the best for the smooth look that I believe that you are looking for. Any one that does glass and is working for the really deep smooth look will use it, Examples of lots of polyurathane is the the Alpine Civic Si, and Mini cooper, They coat all of the stuff in it!!
