I have attached a few photos of my 1979 camper trailer roof I sealed with your RVroofmagic product just a few months ago. I have a couple “before,” along with a “during,” and one “after.” That roof had been caulked over the years by the previous owner, and there were small leaks. This product is amazing. I used it for a horse trailer a few years ago, and I was excited to apply it to this camp trailer. I am a believer! The roof is sealed, and I have peace of mind, and the trailer is worth more now because of it! This product went on easily and I especially like how it is self-leveling – it is smooth and nice now. Great tech support to boot!
