What did you do to your Class A MH today???

Removed Skylight in Bathroom as part of resealing the roof vents. Found a full inch where they forgot to install the butal tape. Trying to remove the remains of the old tape is a PITA. Cleaned all of the yellowing plastic from the skylight and sprayed it with clear paint to hopefully stop it from yellowing again. I can not tell if I have a EDPM or TPO roof. If EDPM it is the thinnest rubber I have ever seen used in roofing, maybe an eight as thick as the roofing on the Hospital where I work. I have never dealt with TPO so maybe that is what Gulf Stream used in 95.
