I'm using rubber extrusions to make a few weatherproofing pieces. I have purchased some "self vulcanizing patches" off eBay which I hope to use but there are a few point where these may not work out.

Does anyone, including any old cobblers, who is aware of a product or technique which will bond rubber to rubber. The joins will not be under much load but they need to be waterproof. Thanks.
