i cannot find the source of a major leak in the overhang of my 2009 Thor Class C Four-Winds, and so am almost certain I will have to end up replacing the roof. I would therefor like to find out what experience people have had with these 3 products. I'm thinking one of these would be better than reinstalling a rubber roof.
Flex Armor
RV-Armor
Rhino Lining - Is it true this coating does not flex? I could see that being a problem on a class C.
