Flex Seal instead of Lap Sealant?

[CHS]

Flex Seal is way overpriced. Went to Lowes the other day to get some of the tape.
20.00 for 5 foot role. I bought the Gorilla (waterproof) tape. 10 feet for 12.98. Seemed like the same thing. I only had to use it for the top of one of the 3 inch black water 90's.
No pressure. It's a rubberized tape like Flex Seal and stuck really well.
That said. I had a leak in the top section of the 90 degree, 3 inch sewer PVC and found that (what it looks like) they heated the 90 from the top to what looks like to increase the bend so the fittings go together. That caused a kind of heat crack in the pipe. Nothing near it that could have caused the crack/melting of the pipe. Really weird.

I used flex seal on small sections of my Jayco 25' roof. It didn't last but one season. The sun in Fl is nasty, separated and lifted around the edges. For small areas, I use the Red Devil Butyl sealant. WE have since upgraded to a class A.
