What is this stuff: Stay Afloat Emergency Form-A-Plug Leak Sealant

So Defender sells this for $28.99 for 28 ounces. Not too bad in boat money terms if it is truly unique and strong, would stop bad leaks, or help slow them and is NOT something ordinary that costs $5 but has been re-packaged into a marine brand for 6 times as much.

Anyone heard of it, bought it or used it? There is no MSDS on the web site and the site states:

?What is it? Stay Afloat is a thick blend of a petroleum by-product sourced from the refining process, which has been severely washed, cleaned and treated. The product works by displacing water and adhering to almost any surface, in water, under water, when water is coming in, ingress, or you want to keep water from leaking, it work in both situations. The product does not harden and can be easily removed for permanent repairs.?

Saw it at B.O.W. (Boat Owner’s Warehouse) 2 days ago.
Brand new product, it may be the ticket..

Ah, different stuff. I saw something pink, shaped like a big plug with breakaway points.
I thought the OP was talking about that...My bad.

It works on almost any water leak except high pressure. It will stop hull leaks but may not hold in the bow at higher speeds. Although it can be used in combination with a patch. I used it on a coolant hose, but loosened the expansion tank cap to it wasn't under pressure. It went about 20 hours before I changed the hose.

Re: What is this stuff: Stay Afloat Emergency Form-A-Plug Leak Sealant

I was involved in a rescue a few months ago where a Cat had gotten a few foot gash just below the waterline and was sinking. We tried two part underwater putty, a Danish foaming product meant as an emergency seal and Nerf style footballs and plugs.. The Nerf balls and plugs worked the best and they are dirt cheap.

Looks an awful lot like the same material as a wax toilet ring which you can get at any home store for five bucks. I always kept one or two on the boat along with a couple nerf footballs.

Re: What is this stuff: Stay Afloat Emergency Form-A-Plug Leak Sealant

I carry Great Stuff, a foam in place product stocked at Home Depot. In 2012, I hit a coral head and poked a hole in my Boat’s port keel just below the waterline. Took a can of great stuff and a rag. Foamed the hole and put a Boat cushion over it until the foam set. Held until I could pull the boat for a real repair.

More than "an awful lot." Looks to me like EXACTLY the same stuff!

Re: What is this stuff: Stay Afloat Emergency Form-A-Plug Leak Sealant

Can I ask, what is a Nerf style football and how would it help me with a big hole below the waterline?

I just know I'm going to feel stupid when an obvious answer is given ☺

We carry cans of great stuff for that kind of emergency as well. Nerf footballs, too.

I'm betting it is the exact same thing, with the enhanced "Marine" label, and modified for marine use by raising the price 500 per cent!

These NERF footballs are very soft closed cell foam toy football. You can purchase them at most toy stores or Walmart type stores. About $7

Hope that helps.

Re: What is this stuff: Stay Afloat Emergency Form-A-Plug Leak Sealant

Basic petroleum wax like a toilet bowl seal. Just listen to the man: Lots&lotsa words - no substance, all guff. Pure marketing!

How much does a harbour official get paid for moonlighting like this? Is the man really an employee of a harbour authority, or is he just clawing for credence :-)?
