I havent found anything better than epoxy and vacumme bagging
I used a 40.00 hand held manual operated vacumme pump you can buy them at your loacal car parts store.

I ran across an article on the net that instructed me on how to use these pumps. The rest of the items you need can be found at your local hardwares store. If anyone is intrested I can try to dig up the article again and post the url.
