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 discus...

How about the Flex Seal tape? I carry some but haven't used it yet.
I tried Flex seal tape a few months after I had already used "Henry Tropicool Silicon roof sealant" throughout the entire roof. Busted a seam on a previous bad repair during a trip. Cleaned the area thoroughly but the tape did not want to adhere.
JUST NOW...(5:30pm 4Aug2024)...I tried it again on a very hot roof. smoothed it out, let it sit for an hour THEN applied a good smather of Henry Topicool silicon sealant over the tape. Waited an hour to let that cure then liberally applied more Henry over that. With that said, we will see how it holds up on the next stretch of road.
Nothing will stick to silicone, not even fresh silicone. That's why it's not recommended for sealing any areas on a camper.
Well, bummer! There I go again believing what I read on the internet. Thanks for that info.
Let's see if this new patch lasts for a little while. I guess now I'm obligated to keep checking in here with updates. LOL.
Replying to myself for ALL...
So far so good. Drove through tropical storm Debby for 2 hours of heavy rain on I-40. Next day of sunshine took a 3 hour tour on mountain roads. While at RV site the roof AC condensate collected in that area as usual. Currently only 550 miles...might be close to 800 miles by the time I get home.
Obviously where I DID NOT clean and dripped the silicon...came off with a good fingernail. Where I did thoroughly clean with alcohol it appears to have a good bond. I picked at the good areas a little bit with my fingernail but did not want to force it off. This is still a new patch so this short trip may not be a good benchmark.
