Frequently Asked Questions
- Can the semi truck sleeper 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.
- Is there a certain glue that can be used in conjunction with the accordion boot?
The rubber boot does not require glue for installation. This is because there is a spring clip embedded it the rubber. When the boot is placed over a flange the spring clip squeezes the rubber securely. The only place you may want to glue the boot is where it meets. This is however optional. To glue the seam where the two ends meet, you can use cyanoacrylate (i.e. SuperGlue). Do not use any petroleum based glues as it will react negatively to the rubber. (i.e. rubber cement). See Installing Accordion Boot for more details.
- I have a pickup that I cut out a section between the cab and the bed. Will your product work for the metal below the window, or is that material to thin?
Yes the boot will work for this situation
