Do NOT use Flex Seal on your camper roof!

Figured I’d post this since I had a troubling conversation with my repair guy a couple weeks back when I picked up my camper after it was repaired following a minor collision last fall. We were discussing my long battle with a skylight leak in the bathroom and I mentioned that at one point I used flex seal spray as an emergency measure until I could do a proper repair with new butyl tape and Dicor and eternabond. He got all exited and told me that the “flex seal is great stuff! That’s the way to go!” And he used it on his parents’ leaky shed roof and its holding just fine. I nodded and told him it’s great for an emergency but from my firsthand experience, it becomes brittle, cracks, and eventually peels off when it’s been exposed to ultraviolet light for more than a few weeks. He apparently wasn’t aware of that. Ive been thinking about that conversation for a few weeks now and figured I’d post a thread about it to inform others who might be tempted to use flex seal as a permanent solution on camper roofs. DON’T!
Even though the tv commercial shows a guy sealing a skylight,
Even though your repair guy or dealer might tell you it’s great,
Even though a website or blog extols it’s virtues,
It is NOT a permanent solution!!!!! Emergency patch? Sure. But it WILL become brittle, crack, and peel off in a few weeks under UV light (sunlight).
So please, PLEASE, don’t even think about using this stuff I place of lap sealant or eternabond.
This has been a public service announcement.
