How to Replace the Seals on Your Hard Top Tonneau Cover


A tonneau cover is a great accessory for any truck if you want to keep the bed dry and free of debris. But a leaking tonneau cover is super frustrating! It defeats the whole purpose of having one.

At the request of many of our customers we now offer a seal specifically made just for truck caps and tonneau covers. And best of all- it’s Peel-N-Stick (no messy glue to contend with)!

In this video we’ll show you how easy it is to replace these seals yourself and you’ll also learn how to create the perfect cut for right-angle corners using the mitering technique and the mantling technique for when two different profiles come together.

Both seals listed in this video are available for purchase on our website, as well as the adhesive cleaner, scraper tool and Super Bonder.

So, grab a friend (makes the job easier) and some supplies and let’s get started!
