Frequently Asked Questions
- What type of rubber is used in your boots?
Our boots are made from high-quality black EPDM rubber, known for its durability, UV resistance, and flexibility across extreme temperatures.
- Can I cut the truck window donut to fit around a third brake light?
No, cutting is not recommended. Instead, remove the brake light and cover the hole, or change how the boot is mounted if you need to preserve the light.
- Can you make the accordion gasket in different colors?
Sorry the boot only comes in black. We have never tested it, but the rubber is epdm and with the right paint is can be colored. From the research the recommended paint should be an acrylic coating specifically designed for epdm rubber. Usually this is paint for roofing. Latex paint should be avoided.
