Question: How do I know if this is compatible for my roof of my Winnie?
Document: Actually this seems to be a good product, difficult to use and messy, and it seems the chemistry is there,  however beware if your rv roof is the ALPHA brand EDPM, as per the manufacture (Pro Coat) , there needs to be a primer installed, or the roof will fail in one to two years. THE EDPM rubbers are not compatible.
Put on the rv roof. It was very easy to apply, and looks great. I am very happy with this product.
I did what it said it would. It was easy to apply. It really makes the roof brand new. We should have used it sooner.
My RV roof looks brand new and I couldn't be happier. Took about 3-4 hours to complete. Dealer wanted $1800 to do this job which was very easy for a do-it-yourself person.
I purchased and installed this last summer on my trailer. It has been on for a year now and after cleaning the roof it still looks great. I expect this to last for the rest of the life of my trailer. I would recommend this to anyone who is looking to restore the roof on their RV.
In the process I was covered with BLACK RUBBER yuck as was the sides of the trailer and the driveway. These all cleaned up fine later on with a pressure washer and some elbow grease. I ordered a full 5 gallons of Liquid Roof to make sure I had enough. I followed the instructions on the label. I had watched a number of YouTube videos on applying the product and had a friend help me.
I bought liquid roof to stop leaks and recondition my travel trailer. This product exceeded my expectations. It was easy to install and cured into a brand new roof! I would highly recommend putting down the primer before instillation since I did have some spots not fully adhere to my existing roof. These spots were only quarter sized and did not effect the overall performance of the new roof.
I let the product sit for an hour. We began applying the product about 7:30AM. The forecast was for 100 degree plus day so we wanted to work in the cooler part of the day. We finished the application and the clean up by 8:30. I had just enough to do my roof and was glad I purchased 5 gallons. I left the roof alone for a week to set in the sun with no rain.
I am a perfectionist, so the job I did is factory quality. Please be sure to use a respirator, gloves, tarps and prepare you work surface and work area beforehand. This product makes a roof slippery when applied so be careful.I am a pro woodworker that restores boats, rv's, furniture and even airplanes. This is not my first rodeo, however it is my last with &#34;Meridian Coatings&#34; !
I bought this and the one gallon kit. I could have managed with the 5 gallons, but, the experience of working with the one gallon kit first provided a good learning experience. I coated the edges and under the vents, AC, etc. with the one gallon kit and followed up two days later with coating the whole roof. I used a smooth roller on a curved/convex roof.
