EPDM is amazing. My RV roof was a disaster. I have been battling leaks for a few years now and no other product would stop the leaks or even last more than a few months. Everything else would peel up after awhile. I used the EPDM with the primer. It rained a week later. Zero leaks! The product goes on easy and covers well. No cracks no bubbles. I am very satisfied and would recommend this product to anyone. The are so many products out there and skepticism runs high. Your company and the product did everything it said it would.
