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?

No solutions for you, but I'm curious to know...

Does it smell like rubber?

Please let us know what you find out, and how well it holds up. I've got a '81 Cherubini with a bunch of leaks as well.

Do you mean the "Flex Seal" as seen on TV? If so, wonder if it's the same formula as 4200 or Dow 795?

I had the crumbling effect also but I cleaned the area better next time and re-applied with several thin coats, allowing a day to cure between. It has been a 90+ percent success. We've had a very wet spring/summer in the Apostle Islands and I have a very dry boat. Been using Zap to help clean the yellowing and it works better than Simple Green or bleach on most areas.

my money's on butyl tape hands down
I got two rolls of Butyl Tape from Main Sail (here on this forum). The stuff is great! I also noticed that Gorilla Glue has started selling a product that seems to be a lot like butyl tape. It is sold as a two sided adhesive tape.

Recently saw some references to 3M VHB tape praised by a marine hardware manufacturer rep for bedding/sealing. (can't remember the hdwe mfr) Looks promising, anybody else seen/tried it? Curious as I have some of those jobs in my future.

I believe butyl tape is quite a bit less expensive, but aside from that what areas would you be looking for improvement beyond what you can do with butyl tape??

About three years ago I had a customers boat on the hill, and he wanted me to check a couple of leaking thru hulls on the boat. He had sprayed flex seal all around the thru hulls, and it was still leaking. It got a HUGE laugh from us boat mechanics. The crap would flake off with your fingernails. Useless crap in a can...

With all the proven products, why would you waste your time and money on a TV scam product?

Not true. You can spray wasp nests with it and they can't fly and you can then stomp them.:biggrin:
Great for ant beds too.:laugh:

Crap in a can........right up there with Bag-o'glass and Bass-a-matic. I like the new Flex Seal Liquid that came out. Now you can smear that worthless crap over even larger areas.
