Making leak repairs is as easy as putting on a piece of tape. Non-reactive Eternabond Tape and Patches adhere to almost any surface (except silicone) instantly and permanently.

Quoted from Trailer Life Magazine,
April 2000, page 74-76.

Whether used to seal the roof of an RV that has seen better days or carried along in the rig for use in case of an emergency, the Eternabond tape offers a viable solution to the age-old problem of sealing out moisture. The product is very effective, and used properly, is much more attractive than slopping the area with liquid or silicone sealers. The company stands behind the product with a satisfaction guarantee.
