It stuck on rubber!
Your review: The ramp to our horse trailer is a thick rubber mat which has gotten slick after a decade of use. I cleaned it well with a powerwasher, let it dry until the next day & put this tape down. It stuck perfectly. The next morning the horses walked on with nary a slip. It's only been used a few times, but isn't showing any signs of wear yet.
It was well packaged & FAR cheaper buying it in rolls here than the short strips I found at ***** & elsewhere. Perfect. Highly recommend.
