Title: Doesn't work unless wood is perfectly smooth
Product review: I tried this product with the 3M outdoor clear film to try to insulate the windows in my heated barn. Within two days after installation all the film and tape was on the ground. The wood trim around the windows was ship-lap (painted, but was somewhat rough on the surface)... this double sided tape did not adhere to the surface and in a day or two peeled away from the wood trim and end up hanging or on the ground.
Would you say this review depicts the product in a flattering or unflattering light?
