### ⭐⭐⭐⭐⭐ Review
*by S***K on 31 July 2025*

The roof of my enclosed trailer started leaking. The 12 year old factory sealant used under the trim had finally given up. After removing all the trim I found how poorly the trailer was constructed. They used rivets every 8-9 inches or so which left a lot of the aluminum skin buckled up; and would have been difficult, if not impossible, to seal. I added a couple hundred additional rivets to make everything smooth, then cleaned all the areas that were going to receive the Eternabond tape. Application is straight forward and easy. Be warned, you need to plan ahead, have a helper if you need one, you only get one shot at placing the tape. After you get it down give it a good rolling. It also worked great on the top-to-side 90° transition; just place it on one surface, roll it to adhere it, then fold it over and roll some more. Pro's: Ease of use, durability, adhesion, quality. This will forever be my goto solution for trailer roof leak repairs. Con's: None really. There is a learning curve to using it but if you've got two brain cells to clank together to make a spark you'll be able to figure it out.
