Let me start by saying this gap hider does its job—mostly. The rubber material is dense and feels durable, exactly what you'd want for sealing gaps against wind and rain. It fits snugly on my LEER 100XL side windows, and once installed, it stays put (after some wrestling).

But here's the kicker: installation is a battle. Out of the box, the rubber strip arrives rolled up like a stubborn yoga mat. In cold weather? Forget bending it into submission without a heat gun or hairdryer. I had to tape mine down for *days* before it relaxed enough to adhere properly.

The 3M adhesive sounds promising, but real talk—it’s hit or miss. On clean, warm surfaces, it bonds decently. But if there’s even a whisper of dust or chill in the air, expect frustration. One strip stuck perfectly; the other peeled like a bad sticker until I added extra adhesive.

At 24-1/8” long, it covers the gap well, but that stiffness makes alignment tricky. You’ll need patience and maybe a second pair of hands. Once settled though? No more whistling winds or leaks—just a clean seal.

Verdict: Functional but finicky. Ideal if you’re handy (and own a heat gun). For plug-and-play ease? Keep shopping.
