## Questions & Answers

**Q: Can this product be coated/covered with the Liquid Roof EPDM product?**
A: My seams on my Motorhome were sealed with this product 10 yrs ago.  My roof was recoated with EPDM rubber roof in a bucket three years ago.  No problem thus far.

**Q: Has anyone used this on galvanized metal roofing?  Lots of seams!!   Some have been caulked with silicone..**
A: I used this sealant on a galvanized camper roof at the numerous seams that were previously coated with silicone. I made sure that I centered the silicone with the sealant. I was worried but took the chance that there would not be a reaction between the two products. it has been two years now and the roof is still fine

**Q: What size is the roll of tape**
A: The tape is 4 inches wide by 50 feet long. There are three sizes to choose from, 2" x 50' long, 4" x 50' long or 6 inches wide by 50 feet long. It's designated on the packaging as 2-50, 4-50 and 6-50. Works great. You can put it on and done!  When you use lap sealants by Dicor or other makers they take up to a month to fully cure.

**Q: Would this be good for a large mobile home roof ?**
A: I think it would be good to use on any camper or mobile home roof to help stop a leak, especially at a seam, but it would also be a good idea to seal around the edges of the EternaBond with a bead of DiCor sealant.  That's what I did on my aluminum camper roof and it worked like a charm.

### ⭐⭐⭐⭐⭐ 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.
