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

If you own an RV you need a roll of this stuff!

This stuff is awesome. I use it on seams and to seal things on the top of our RV. Kind of like the duct tape for roof and seam repair. The great thing is that it seems to be permanent. I used some 2 years ago and it's still doing well.
