If I leave my CMP glass fuse models in direct sunlight at around 80 degrees, it will get soft. I keep them out of the California sun.

It is normal for a mass production type of glass fuse to "oil can" as its known in the composite model world. This is not a problem in flight. Its only seems to be a problem because someone squeezes the fuse at an unreinforced location. This oil can effect bothers some people.

My little 109F has the oil can effect at the rear of the fuse (old layup). It has minimal wood, a servo tray, wing bolt mount and a rudder post rear of the firewall and is more than enough for abusive flight.

But it still bothers even me to have a flimsy fuse. My buddy HVACMAN and I have configured a layup sequence that almost eliminates the oil can effect in a fuse without added weight or wood. I tested it in the Spitfire I have posted here somewhere.

Still not to worry about the can thing.
