Just wanted to let everyone know I was at the RV Supershow in Cleveland Ohio a couple weekends ago and ran across a new waterproofing system for an RV. There is a company close to Akron called RV Roof Shield. They offer a 12 year warranty on the system against leaks and the product peeling off your roof. I scheduled my coach last week and am very pleased with the job they did. They were very nice and knowledgeable. I think this is the future of RV roofing. Look them up on the web. www.rvroofshield.com
