What type of roof sealant is this?
Hello everyone, I'm not sure if this is the best forum for general RV maintenance questions. But I didn't find one that looks specific to maint/repair. Let me know if I missed it.
Last spring I purchased my '94 27" Thor Chateau 5th wheel RV. I need to do some roof resealing before I head out again. The roof is a single aluminum sheet with no seams and no coating. But it is sealed with something around the vents, skylight, and at the corners, etc. It's in decent shape overall, so it only needs touch ups.
But I don't know what product was previously used. For 28 years old it looks pretty good, so I doubt that it's all the original sealant. But it's also brushed on and kept fairly neat. The material looks and feels a lot like latex caulk, but I think it is perhaps a polyurethane or other RV specific elastomeric product.
It also looks like it goes on more like a paste than a liquid. And I want to stay with that, since I don't intend to coat the entire roof, at least not yet. And the self leveling lap sealants I've seen look too runny for what I want to do.
I thought about trying a small container of Flex Seal, but I read that it's kinda soft and doesn't really last very long. Whatever is already applied seems very tough. It's a bit flexible, but hard to penetrate and pick at.
Any suggestions or recommendations much appreciated!
