Ameri PVC Plastic Rain Gutter for Cars, Vans, and RVs, Easy to Install Flexible Drip Rail Molding to Control Water Runoff (16ft, Black)

Super strong adhesion. Being rolled up it kept some of that shape so heating it up with a hair dryer before putting it on allowed it to not have wrinkles in it when stuck to a flat surface.

Do Not Buy. This product will not work as expected since the 3M tape was not applied smoothly therefore water will get underneath it and ultimately it will probably not stick and not function as intended. See the photo. Maybe I got a bad batch but certainly wish I would have noticed before I installed it. very disappointed.

The gutter itself is fairly decent. It's rubbery, flexible, and seems similar to other gutter material I've bought. It was a little warped from shipping, but a little bit of heat from a blow-dryer or heat gun fixes that. The adhesion was good, though I added some glue to ensure it sticks long term.

never unwarped... tried hair dryer and everything. it's been a month of laying out on flat surface and it's still curled and warped from being packaged.

Like everything on Amazon these days, is one of a dozen seemingly identical no-name versions of this molding. The one I bought last time worked well but is no longer available, and I needed more for the other side of the RV.The adhesive backing on this one is so uneven that it cannot be pressed flat against the RV wall. Water runs behind it like it's not even there. Gonna roll the dice with one of the other "brands".

Fell off without getting through one winter. Didn't even make it to the rainy season.

Did not stick. Hard to install. Do not buy this item.
