Hi:
Yep, the sealant method is simple and it works great. Only, instead of aquarium sealant which may be hard to come by, use simple silican bathtub sealant found at Home Depot or Lowe's or your local hardware store.

Here is the routine. Cover the wing center section with saran wrap (or equivalent) holding it in place with masking tape. Get it pretty tight. Then run a rather heavy bead of the sealant along the saddle. Mount the wing and tighten it down being careful to maintain alignment. Let it sit for 24 hours. Then remove the wing, remove the saran wrap, and with a sharp blade cut away the excess sealant (you only have to do the outside unless you are really a neat freak), then go fly!

This stuff really takes heat well. You can use it for gasket material on your engine without worrying about it burning away. I have used it as a gasket between the exhaust port and the muffler without any problem. It lasts for years!

Good luck,
Phil
