... what about using JB Weld to keep a piece of aluminam over the hole?

Also, when you pulled the plug, did the beads just drain, did you have to shake it etc....?
It did for me - but then again my FW was in pretty bad shape and had run real rich for awhile, so the beads were fairly clogged with carbon. Cats get pretty hot, I'm not sure how well JB weld would hold up under several hundred degrees. I put a paper bag under the hole, the beads took their time to come out, I used a rubber mallet to help them along.
