Just the same, I know quite a few folks who thought all "Silicone" was the same,
and they bought their's at Home Depot to save a few bucks. OOPS! The home
version releases ACID as it cures. Pretty hard on boat hardware.

I think I get your point, and that's why I've been asking for reports
from users. Still, the 3M "Marine" silicone sealant that I bought at
West Marine just a few months ago was acid cure and double the price
of hardware store too... And, FWIW, 5200 releases solvents which may
include toluene, heptane and acetone. I'm still waiting for the
adhesive / sealant that sticks to everything, melts nothing and cures
in just the time needed... I don't know if this Silaprene stuff is it,
but the ability to stick to unprimed metal and other interesting
properties (see Bob's post) could make it a useful addition to my bag
of less than ideal goos.

My advice is spend a few days and become knowldegable sealant-adhesive
user. It took me nearly a month of calls to tech guys, reading
Technical Data Sheets, crusing websites to get a good understanding.
WM....and anyother retail boat store. They will carry the product
that provides the most profit and is "most popular" for everybodys
use... You know, the fit all product.

Regarding silicon products. When I installed my polycarb fixed port
lights I had to use silicone. After a few weeks I narrowed a few
products down and started calling the manufactures. Then I called a
couple instate big city commercial window installers (Union Shops of
course). I chose a product used to "glue" 4'x8' windows in sky
scrapers and keep Lexan in place in high security prisons. The tech
guys refered to it as "structural silicone" It has the same density as
lead (JK). It was a Dow Corning product can t remember the #, maybe
DC-735???

What im getting at is the last place you may want to seek info is from
WM or other boaters........ Go to the experts and tell them the your
aplication n specs and see what happens.

It s not going to happen........... get the right goo for the right
job. And always remember when you use "boat life" or a Universal Goo,
it will always be a compromise. Personally i do not want to compromise
my projects.
Fair winds and good gooing....

Perhaps the stuff you have in mind is Dow-Corning 795. I've used it
quite successfully to attach plexiglas deadlights.
