## Customer Reviews

### ⭐⭐⭐⭐⭐ Rv roof sealing
*by J***R on September 7, 2025*

I used on an epdm rv roof. Worked well and coated nicely but took a bit more than expected. I would use again in the future. I do recommend following guidelines of cleaning and using a decent primer. I read reviews before buying and didn't see any bad results and I felt cleanup was simple if done quickly.

### ⭐⭐⭐⭐⭐ Good
