While I frequently see products in stores promoted as "As Seen on TV!" I generally do not take that as a positive product endorsement. 
There's an earlier thread on it
Flex Seal
I've recently, successfully I might add, using a product called Flex Seal, stopped a whole lot of deck leaks on my 1980 Hunter Cherubini. The down side is yellow staining spots in the gel coat too. LOVE the waterproofing, not the stains. Anyone have a solution?

MSDS and advertising conflict regarding what this stuff is - one implies butyl while there is an ad description saying it is a proprietary silicone based mix. If we can’t figure out what is is, why would you want to use it and how would we know if it’s the ‘right tool for the job’?

I am not ready to trust "SealFlex" even if it kept the screen door bottom dinghy dry while speeding about on his outboard. There is something just not right. Perhaps it is too much like those late night sale commercials aimed a the 2AM crowd.
In addition to the standard wood Bung, there are these ideas.

How To Stop A Boat From Sinking - BoatUS Magazine
Quick action and three items can keep your boat afloat in an emergency …
I asked them about that, but they said, "This amazing product can't be found in any store, it's available only through this special TV offer. And if you act now..."
Sadly, @jssailem, every last koi ended up being a fine lunch for our neighborhood river otter. I think he enjoyed them with a side of fava beans.

SS holding tank and urine don't mix well. Plan on another round of Flexseal or a new plastic holding tank.
I havent had the opportunity to use it but I have handled the tape. It's very stretch, thick and sticky. It will stick very well to most surfaces but I have a feeling it would leave a mess behind if you tried to remove it or left in the sun. My first thought when I picked it up was that it might work well to seal a hole in a boat in an emergency. Who wants to give it a try?
Tell you what, I’ll drill some holes in the hull below the waterline and give you a full report on how well it works.
I have used Flex Seal spray on Caulking to try as stop a window leak
It deteriorated in a week of UV exposure.
I have Flex Tape stowed near my PSS bellows. The reason is if i get a leak in bellow i have no way to stop that leak.
Along with that Flex Tape, I have Duct tape to over wrap it plus wire ties.
Over done?
Not if i want to keep my boat afloat.

Remember the seal made is to stop the back pressure of a leak.

PS:
A neighbor used flex seal to seal vertical windows on his house boat. He used it six months ago and no leaks; I am skeptical about the stuff; going to try Dow 795 UV next time I reseal my deck skylight. Using Captain Tolly's penetrating seal until I muster enough enthusiasm to do this job again!
That's me ! And that's why I have to go back and update my post about water treatment. I'm up too late, but my brain goes to bed early.
