Hi. I am in the process of reworking a 1974 montauk and have found a great way to bed everything. I have used 520, dolfinite and most plastic stuff on my past boats, sail and power, but none like this. Check out the following link, this is a no mess bedding for metal, fiberglass or whatever, and cleans up with paint thinner.

Yeah good stuff I bought three roles of it for under $10 at my local weatherproofing store

Hi. As a contractor and over 70 the stuff at the local box store is not as flexible as this tape and will dry out.

I was recently reading an article about this subject. Butyl rubber is what we used before 3m introduced their great products. I've been sailing for 40+years. Butyl rubber was used for through hull fittings as well as sealing deck hardware. In a test , butyl lasted as long as 5200 and was still pliable. I by it from a plumbing supply. The tape type has to be used like silly putty, you make to or three layers , roll it like a doughnut around hole. Make sure you have enough on to squeeze out all around as you tighten.
When I think about how much has been debated and discussed about 3m 5200/4200/poly sulfide/and that nasty stuff called silicone.
Funny when you think about it, butyl was hardly even mentioned in any comparison of sealants/caulk.
Happy New Year from the Texas Coastal bend.

Tim you where right on the spot with your observations. I have not done the test you have but I had a old 41 charles morgan yawl for 25 years and always used definite and it dried out very quickly and became brindle. Wish I had used this stuff then.

The web site I gave is an interesting one and links to cruising people which test it everyday.

Hi Tim.
One of our friends, Louie, has used butyl rubber for a long time. Seems like it is being rediscovered. Another just used it for cabin windows on a Pearson Triton.
I discovered two rolls of butyl rubber I ordered early this year. They were stored in a very special place.
Polysulfide is another great one that has been put aside. I think often of the equipment on my boat bedded during my "5200 period". of course I knew at the time that equipment was perfectly installed and would not need removing.
