I have a used 2009 Fun FinderX 16. The roof has been patched in several places with what appears to be Eternabond tape. there is caulking in the front corner which was applied to seal a leak by a PO. The roof is arched and appears to be solid. AC and all the usual vents through the roof. As far as I can tell, the roof is TPO. After reading all the posts on roof sealing, I am thoroughly confused.
My question is; Is there a sealer that I can paint over the entire roof as it sits that will provide adequate water protection for several years with proper maintenance? The trailer is in the LA area and parked at home in the sun.
If not, What are my options?
