Looking for adhesive to make a liner patch

[GBBUDD]

There's only one way to patch rubber epdm and then there are bandaid. Here is how to add adhesive and seam the only difference is to make the patches round. It's one of those things rubber ripped easier if it has 90 degree corners on a patch . No I realy don't know the physics to it but it's what it does.

Yep, I've made patches on many tire tubes over many years. You never use a square patch, always round off the corners.
