I have a 1992 Fleetwood Bounder, 28'. My late husband had coated the roof with Kool Seal Elastomeric in 2003 and now it has blistered, like little volcanoes. I am trying to take it off but some is still sticking really good. Rubber roof underneath appears to be in good shape, it is tan with a mesh fiber below the rubber. How can I tell if it is EPDM or TPO in order to repair three very tiny spots? Best way to clean roof off, dish soap,laundry detergent, protectall cleaner for rubber roofs, etc.
Thanks, in advance, for any help.
