I can never keep this straight, sorry. There are two types of epoxy/resins used to make up a glass fuse, they don't stick to each other very well. There is often a releasing agent film left behind from the mold too so your fuse must be cleaned real well or even if you have the correct resin it doesn't stick well.
Because I have never been able to keep the two straight in my head I started using gorilla glue for a lot of my glass repair. Reinforcing behind the fire wall is a very good idea. Do some testing on your fuse to make sure what you use will stick correctly.
Hi Gene et al,
Hope you all had a great Christmas and an even better New Year awaits us all.
Epoxy sticks to polyester and itself. Polyester only sticks to polyester. All surfaces need to be abraded/"roughed up" and then cleaned with acetone to remove any mold release agent and ensure a good bond prior to repair.
Cheers,
