I just wanted to send you a testimonial email about your product. We bought a ’99 5th wheel only to find out that it had a leak 3 months later. I had to repair a section of the roof decking and replace a 3 foot section of the membrane leaving a seem on the roof. After making the repairs I coated the roof with liquid roof and waited until after we had a rain storm to send you this testimonial. I am happy to report that after an overnight rain storm that dumped over an inch of rain I went in the trailer to find it bone dry! The product was easy to apply and I have even used the left over material on a couple of other projects after placing it in the freezer for storage. I would recommend this product to all RV owners and will probably coat the roof of my next RV with it.
