First off, let me say this gap hider does its job—when it finally stays in place. The rubber material is dense and feels durable, but boy, is it stiff out of the package. Rolling it up for shipping means you’ll need patience (or a heat gun, as one reviewer wisely suggested) to flatten it properly.

Installation is straightforward—clean the surface, peel the 3M tape, and press. But here’s the catch: in colder weather, the adhesive struggles to bond. I ended up using duct tape as a temporary clamp for 48 hours. Not ideal, but it worked.

The fit? Spot-on for my LEER 100XL’s twist-out windows. Once secured, it seals gaps tightly, blocking dust and reducing wind noise. Just don’t expect a quick fix—this is a project for a warm garage day, not a roadside emergency.
