## 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.
