a marine specialty store can get you epoxy or resin, which will waterproof your cage. (like west marine, or your local marina)
It will also strengthen your cage (especially if you lay fiberglass too)
The epoxy is somewhat dangerous, it must be catalysed before it will harden and the catalysts are nasty stuff, dont get in on your skin, and rush to the hospital if you get it in your eyes. Make sure to let it sit for a few days to air it out.
