Frequently Asked Questions
- Will the truck window doughnut work with thin metal or wood frames?
Yes, but there must be a flange no thicker than 3/16". For wood or thick materials, add a metal strip (like aluminum flat bar) around the opening for the truck window doughnut to grip.

Your complete satisfaction is very important to us! We guarantee that if you do not like your merchandise, or it is broken, you can return it and get your money back. This 100% satisfaction money-back guarantee is good for 30 days.
- 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.
