I think the title tells the story

The brush is an Omega Badger Shaving Brush
The materials appear to be a chrome coated plastic collar on the brush handle
some kind of aluminium or similar for the rest of the handle
and the knot of coarse has a white plastic base - about 20mm diameter, depth about 10mm

So the problem now is what glue to use to fix the problem
When it first happened I did a clean up the Silastic that held it together
Yes you read it right - Silastic

There was a considerable gap between the brush knot and its seat in the handle
The silicone went about 1/3rd of the way down the gap - about 20mm depth
I am guessing the brush knot just sort of sat there held on by Silastic

I have tried Tarzan's Grip with little success - lasted 3 days
So now I want to know what glue will work would be best to fix the problem

Any thoughts or guidance much appreciated
Bought from The Shaver Shop in Brisbane ... no endorsement from this shaver
