Tenacious Stuff

It is tenacious stuff. It sticks like crazy. It is easy to manage with the backing supplied but it is necessary to align it properly before applying it because it sticks like crazy. However, it is capable of being creased or folded to restore alignment if alignment is not perfect. But it will stick to itself like any other tape and cannot be easily removed after application without causing some damage.

The answer to leaks on RV

My brother tried flex seal and multiple other products, leaks continued. I cleaned up his "mess" (removed flex seal, etc...) applied tape as directed, problem solved. Amazing product

When you install this on a clean surface on your RV roof it is permanent. It is great around the skylights or along the edges. You'd better get it right the first time because there's no lifting it back up. I've been using this EternaBond tape for years and I love it.
