Review on Gorilla Waterproof Patch Black (Model 4612502) by Tony Stennis

I used this to repair a TPM (white membrane) roof. Very sticky thick sticky glue like crazy at 50 degrees and up. Cooler temperatures may require the application of gentle heat (such as a hair dryer). The adhesive is so thick that when you press the patch with your fingers, some of the adhesive sticks out around the edges. We've had some snow and rain lately and the roof patches held up until I could get a more professional repair.
