EPDM is an awesome product and everything that is described on their website. We encountered a leak on our 22 travel trailer and Googled roofing products. We found the Rubber Roof from EPDM and had to try it based on all the information and testimonials. We completed the prep, taped off all sides for spillage, and proceeded with the squeegee and roller (be sure the roller is low nap). After installing the product we had bubbles. We contacted EPDM and they stated the bubbles would disappear during curing. Sure enough, they disappeared. Good thing, as we applied another thin layer to the front and back where the siding and roof meet, as we had removed all of the old caulking and applied new caulk, before applying the Liquid Roof. The roof looks fantastic and we will now have many more summer camping trips ahead. Thank you for such a reputable outstanding product.
