Flex Seal

[mark5w]

Has anyone use Flex Seal on the vents and other thru the roof openings? It looks great on tv, but not sure it will work on EPDM roofs.

I used it on an abrasion / wear point from my RV cover flapping over the winter.
The area had worn thin and I built it up with white flex seal and you can't tell there was ever an issue. Time is the ultimate test. It's only been 2 months

I've used it on my previous travel trailer roof but I wouldn't use it again because the sun dried it out and the flex seal started to crack and peal everywhere.

Same results on a couple garden fountains. Worked great for a month and then started to crack and peal

Is this something you could use Eternabond for? I've used it almost everywhere I was concerned about water leaks.

On our new unit the week after we brought it home I enterbonded every seam on the roof great stuff

Frank, did you use it around the skylights, fridge vents, and plumbing vents also? If so, how wide was the roll you used?

Every where 6 inches wideI also installed smoke colored vent caps the sun down here hates those white caps and will kill them in two years After I put these on the last unit I never had that problem again

Thanks Frank
