I have tried this twice and found that the application of the epoxy is very important. The first time I did it, I left extra epoxy, figuring I would sand it even. I am sure this is obvious to the experts, but when you sand two materials that are of different hardness you will run into difficulty. The epoxy resists sanding but the relatively soft hard rubber gets removed easily. You end up with "humps" of epoxy. The second time I tried this, I used a razor blade to level the epoxy, so little sanding would be required. This worked much better.
