I guess I do not understand your comment, as you did not include the basis
for the statement. I have used cases of the stuff and find 5200
extraordinarily useful. However, it is NOT a sealant. It is a very very
tenacious, all temperature, gap filling, permanent adhesive with limited
flexibility. Used correctly, it will last longer than the boat. It is
expressly useful for adhering different materials having different expansion
coefficients.

"Silaprene" is the name for about 200 different formulas, some of
which may react badly with what you are bonding, or have other issues.

That said, 5200 is not a good general purpose adhesive, either. There
are very few "good" uses for it on a boat.

You are right but, owning a boat in which 5200 was used for everything by
the PO, I think all boat owners should be required to get a note from their
mothers before being allowed to buy the stuff.

It's not a good general purpose adhesive because it's permanent. I've used
lots of it also, but only for things I don't want to ever unattach. 4200 is
better for that sort of use.

I don't believe he used the word sealant.

There is a solvent for 5200 which is also magic for getting 30 year old
striping tape residue and similar stuff off. I forgot the exact name but it
is something like "Marine Formula". Google should turn it up.

Like I said earlier, "some" vasectomies are reversable.

You can't count on it, though.

I would also wonder what effects a solvent for 5200 might have on
fiberglass, and other materials that it might contact. Do they claim
it will penetrate deeply and release 5200 that is holding something
such as a chainplate? I'd just as soon use something that doesn't
leave a question that may have an unhappy answer later - far from
port. It's not as if there aren't proper alternatives.

How about getting specific?
Like where you use 5200 as an adhesive and where you use something
else.
Same use of a one-for-all solution happens a lot on the automotive
side. Since Blue RTV came out it's found it stuck between every part
put together by some mechanics, whether it serves a useful purpose or
not.
I promise not to mention WD-40 - or MSD's.
Personally, I'm pretty particular about lubricants and caulks, but
sometimes slip with the small squeeze tube stuff, because it's prone
to harden up after being opened.

I agree with you, 5200 is not a GENERAL PURPOSE material. Guys like
you should not use it... Damaging deck hardware & fittings? WTF??!?

For the rest of us, 5200 is great. Shucks, 3-M makes a huge number of
very very useful products.

You should have stopped right here, before your "inner stupid blowhard" took
over once again.

No, that's not what I said. Guys like you should have someone read and explain
things to you. When you bed deck hardware and fittings to a fiberglass deck or
hull surface, removing that piece without damage to the fiberglas is not always
a complete success. And if the surface is wood, you may as well have replacement
wood at the ready. It's going to make a mess.

For the rest of us, 5200 is great. Shucks, 3-M makes a huge number of
very very useful products.

Nobody said 3M doesn't make a huge number of great products. I didn't even say
that 5200 was a bad product. I plainly said that it simply isn't right for the
majority of places where ignorant buffoons and hacks such as you slather it on
things indiscriminently.- Hide quoted text -

Hello.......
Foul mouth Bob here,
I chose to NOT use 5200 to bed my through deck chain plates becuase
the 3M TDS numbers were too WEAK for my liking. I read the many,
"youre an idiot for using 5200 to bed chain plates. It will eventually
fail and will be hell to remove !"

Well after reading the test results of several products I
agree................ 5200 is weak comared to other products and will
fail. So why not use a "better" product? Duh.......

So I chose Silaprene. When I talked with their tech guy he said one of
the more common uses is glueing truck trailors togehter. extreame temp
range/vibration/expansion-contraction. Ya nkow the 40' semi boxes
rolling down the interstate at 70 mph. They dont use 3M 5200.

Now about that link from the Good old Boats.......... Why do you think
that ONLY BOat LIfe and 5200/4200 are specificly named yet no other
company products get a mention??????

No if I was bedding a below the water line through hull...........
then Id use 5200! why, cause the product is better suited for 100%
immersion. Things have come a long way since Dolphinite.

I have used 5200 on many things, but not "indiscriminently," and never
damaged anything with it, nor damaged anything trying to remove it.

In fact, I have a hard time picturing how you could do that... you
must be a lot smarter about how to damage boats than I am. But then, I
can generally remember what I said yesterday, too.

Bull, unless you are in the habit of applying a layer of wax on the fiberglass
so The 5200 never actually bonds to it.


Actually, I keep a layer of wax on most of my boat's surfaces. But not
in places where fittings are mounted & bedded. Is that what you do?

My method in removing 5200 has been to use a thin blade to cut it
free, then use a small wire wheel to remove it from both surfaces.
It's time consuming, but I've only had to do this a few times. Only
once do I recall a 5200-bedded fitting leaking and requiring re-
bedding. A pretty good record IMHO.

Still, there are a lot of places that 5200 isn't really good to use.

you can always handle what you get in return.

Has anyone tried DeBond Marine Formula? I have been using it on 6 to 8
month old 5200 and it works great. Had to remove a couple of fittings that
I had installed a little to soon and had to take them off to get under them
to work. Came off the fiberglass clean with a little prying with a
screwdriver and a plastic wedge with no mess and no damage to the FRP.

Just scored around he edges with a razor knife, sprayed on the DeBond and
waited about 5 minutes. Lifted one corner with the screw driver, inserted
the wedge and lifted the other corner. I don't know how it did it but it
penetrated across both surfaces of a 3" wide area of 5200. Might take 2 or
3 applications to make it across a wider area.

Also good for cleaning up those drips that seem to leap across the boat.
