## Description

Mobile Home Bottom Board Material Mobile Home Polyethylene Underbelly

Review: Best tape for under belly of RV - Good adhesion which I increased with adhesive spray. This allowed the tape to adhere to the steel structure and the cover that was already in place. This tape was wide and thick enough to be a permanent undercover.
Review: Good - Good price, worked well for rv. Wish it was a little thicker material. Not as thick as the stuff that was removed. Haven't tested it enough to answer about its durability but it seems like it will be fine.
