Flex Seal To Stop Leaks; Advertised On TV; your experience

Used the stuff on a lapseam joint on my aluminum roof last winter.

Worked for a couple of months. During a trip this summer on the rough frost heaved roads of Alberta, it cracked right along the seam again.

I will be up there this weekend with the heat gun and scraper to get all of that stuff out of there and do it right.

I would strongly suggest using it only as a temporary "on the road" fix.
