Review: Check your measurements - This worked perfectly for my 1977 Airstream compartment doors. The remake of the gasket that is supposed to fit (in the pic door side) doesn't quite fill the gap. I made sure to measure all the gaps and pick the correct size, and this combined with the D-Gasket from VTS sealed the doors when closed. There are similiar products for much cheaper per ft. but I couldn't find the same size for any less, so it's worth the money for the right fit.
Review: Great for replacing sheet material camper windows - Used this to replace the front (polycarbonate sheet) windows in a Fifties Silver Streak Clipper. The material grips the edge of the aluminum skin well, and the "bulb" is soft and supple and seems to create a good seal against the polycarbonate sheet. I guess I will just have to wait and see how it holds up to weather and UV rays, but thus far I am completely satisfied with the quality of this product.
