I've been using one of the other Hysol products with very good success.

McMaster-Carr (www.McMaster.com) has the applicator gun for $20, 6" mixer nozzles, 12 for $9 and about 12-15 Hysol products at around $8.25 each (50 ml). For about $80-85 delivered, I got the gun, nozzles and 6 cartridges.

I've been using E-20NS, a non-sagging white epoxy (they say light tan) which firms up nicely in 20-30 minutes and sets hard in about 2 hours. It's like a rock, maybe harder than you might like. This particular one is called a metal mender but it holds tough on everything. There are others with other working times. The number is the set time and McMaster has some descriptive data. Search on Loctite or epoxy. They don't seem to carry the 9xxx products.

I used just less than one cartridge doing the entire interior structure on a Top Cat including the nosegear formers.

Go to Loctite's site to read the tech data.

Try'em out.
