THIS PRODUCT IS NOT SUITABLE FOR EPDM OR RUBBER ROOF MATERIALS.
The product is non-returnable, so I am out the cost of a product I cannot use.This product was recommended to me by someone I trusted who was unaware that it is not usable on EPDM/rubber roofing. This info is not included in the main product description (but it is mentioned in the fine print “details”). I found this out right after I placed the order, and I immediately tried to cancel the order, but the product was shipped anyway the next day. I should have been more meticulous, but the fact that I was unable to cancel an order that had not yet been processed is unacceptable.

Chances are you can go to your local hardware store and buy a similar product for $12 or $13.
