Since I recently installed a mini split air conditioner on my 97 class A winnebago, linked here
, I will be removing the rooftop air conditioner and sealing up the hole, and I would like feedback from you fine folks.
The plan is to use a piece of FRP, such as found on the walls in gas station and restaurant bathrooms. I'll be sealing it with 6" Quick Roof Extreme, which I'm told is similar to Eternabond. First I'll prepare the area with eternaclean and eternaprime. Last, I'll use newflex 311 to seal down the edges of the tape. Does that sound like good way to go?
Second, the filon sheet on the roof is intact, but it's dry and has completely lost it's gloss. Should I go about restoring the filon before sealing up the hole, or would it be better to stick the tape to the dry filon?
If it is recommended to stick the tape to a restored surface, what should I use to restore the filon? One shop suggested any sort of marine wax. Suggestions welcome.
Thank you in advance, everyone.
