Frequently Asked Questions
- How much capmer shell window sealdo I need?
This material is sold by the foot. To determine how much capmer shell window seal you need, measure the full distance around your cab or window opening. Most full-size pickups need about 13–14 feet, while mini-trucks average around 10 feet.
- Can I keep my sliding windows and still use a capmer shell window seal?
Unfortunately, no. The slider windows must be removed because the capmer shell window seal requires a clean flange or wall to attach. Sliders block access to this area.
- Can the capmer shell window seal be painted?
We only sell black boots, but EPDM rubber can be painted using an acrylic roof coating rated for EPDM. Avoid latex and petroleum-based paints.
