I think that's what it's called. It can increase the interference on the bearing enough to close up the internal clearances when cold.

Thats the green stuff right?

The green stuff I use for relatively permanent fits of things like bearing races is Loctite RC/620 retaining compound for high temperature cylindrical fits. There are other brands with the same application. I've tried it witn loose Commando main bearings in race engines, but it didn't last very long. To be fair to the Loctite, the bearings were pretty loose. I ended up pinning them instead (a la Dunstall), and that worked well.
