Clear Tape: I used the same kind you use with wrapping paper. I covered all the frame included sides. The water does roll right off the tape but, the tape doesn't stick to the screen very well. You definitely need to cover the spot where the frame and screen meet. A little water did seep through, but not to bad.
UPDATE (6/11/08): I still use Aleene's Glue. I make sure to apply it were the screen meets the frame (all the way around!). It stays tacky on the frame. I just cover those parts with tape. This technique keeps the frame about 95% dry when I give it a quick rinse under water.
