In the US anyway, the traditional brand name is "Pliobond", which is more
towards yellow than brown, but could be called either color. Pliobond is a
solvent-based rubber contact cement. It is made by Goodyear, if memory serves.
There are a number of similar products on the market, but I don't recall thir
names.
Avoid water-based contact cements for use holding rubber to metal (or plastic)
in a camera. Far too weak, more intended for holding flooring to plywood
subfloors than camera repair.
How to tell solvent-based from water-based? Read the warnings. If it talks of
toluene and/or petroleum distillates and the like, it's solvent based. If it
talks of ecological purity and low volatile organic solvents, it's water-based.
Another alternative, for use if Pliobond fails, is "Shoe Goo", made by Eclectic
Products (technical assistance, 800-767-4667 in the US and Canada only). As
the name implies, it's intended for shoe repair, but it's used for far more
than that. It's very aggressive, and I would practice on something
non-critical first.
