RV Rain Gutter 1/2 ”Height, 26’Length Plastic Drip Rail PVC Rain Strip Roof Rain Diverter, Drip Rail Molding Adhesive Backing, Flexible J Shape RV Trim Molding for Car Van Door Motorhome

The product seems good from a fit and durability’s standpoint. The adhesive is a waste and completely ineffective.I followed the installation instructions to the letter. And the next morning the pieces I put in place the previous day were on the ground.The adhesive backing was still tacky, but it didn’t adhere to brand new and perfectly smooth and clean fiberglass gel coat. I like the rubber and profile but will need to find a different adhesive.

Adhesive was on wrong side of the gutter. Unusable.

Set on a shelf for a very long time trying to pull off the backing to the sticky part and it stuck to the backing the red pull tab was glued to the black rubber and ripped the product my first clue should of been how dirty the packaging was I could tell it sat for years on a hot shelf

10 feet into the installation, the adhesive started separating from the gutter. Left with adhesive on the RV that wouldn't also adhere to the gutter. it was a nightmare to remove the adhesive from the RV.

The tape on the back sticks ok on flat surfaces, but it didn't remain stuck where the surfaces curved. If the adhesive was better then I would have rated this higher.

The first problem started about 3 feet into the roll. The adhesive foam came off along with the backing for about 18 inches before we noticed. So all that we had installed had to be torn off and we lost all of that part of the roll and started over. Knowing to look For that problem, we were able to catch it the two other times the adhesive started to peel off of the rubber with the backing. All seemed well after that. This morning, we got up, and the whole thing was on the ground. Apparently the adhesive failed. Absolutely not useable.

3M it isn't.When first pulling the tape backing, some of the foam tape was coming with it. I finessed a bit and was able to keep some of the sticky part intact. A few feet in, it all came off.I picked up some liquid nail and a caulk gun.The first few feet I stuck with it's tape, the remainder with Liquid Nail.After putting away the tools I noticed that some of the adhesive was starting to come off and by the next day anything that wasn't installed with Liquid Nail was hanging off my gazebo. This weekend I'm going to finish the install with the LN.This would get another star without the less than worthless adhesive backing.
