Thanks for all the replies on trailer tires and boat polish!

OK, here's another question.

Evidently on this Marquis 22foot'r, someone had either added a bow
railing, or did some kind of repairs. I noticed inside the cuddy where
you could see water stains, evidently from leaking though the edge of
the roof cap. Not damaged but stains. On closer investigation, I see
where someone had run screws into the cap and all is solid.

BUT!
Underneath the railing supposts, it's just metal to fiberglass and
nothing in between.
*ugh!* Which I find quite odd. I an thinking there should be some type
of gasket material in between, like plastic, rubber or the sort, to
keep water from leaking in.

i know, these mounts come in all shapes and sizes and finding and giong
to a dealer and saying "Gimme some railing gaskets!" wouldn't go over
very well.

Is there any source on where to go for this kind of stuff, or do you
make you're own?

I can make them, I suppose but I didn't really care to cut up an old
truck mud flap, (well, maybe as a last resort) ?:-)

And I would like to make it look like a neat factory job, instead of
cobbery.


What do you all suggest?

Thanks!

It's not uncommon to mount the rail directly on the deck without a
rubber gasket beneath.
The important part is to squirt some Sikaflex or other sealer into the
fastener holes to prevent water from wicking into the interior of your
boat, a cored laminate, or etc. (Don't use 5200 to seal the fasteners
unless you are *positive* you will never need to remove them. You can
use 4200, but not 5200).

Even if you jammed some rubber under the rails, you would still have to
deal with a propensity for water to creep down the fasteners. Assuming
that the fasteners have a "head" that protrudes above the stanchion
brackets, a layer of rubber between the bracket and the deck may indeed
keep water from sneaking in under the bracket, but won't prevent
wicking.

I've seen it recommended to use oil when driving SS into glass, to
prevent galling. Do you know of a respected FAQ(s) for attaching
fittings to different boat materials?
Thanks.

Chuck, I understand the idea of "wicking" . These Stainless screws are
countersunk into the brackets, and I always thought there was some kind
of gasketing underneath them. Well, I suppose I've seen them both ways.
one reason I was wondering about the gaskets, is that it seems like
this bow railing really doesn't fit right. OH, it looks good but the
stanchion brackes are sort of mounted with the contour off the cap
around the bow, and don't actuall fit flat to the surface of the cap.
Like they just arn't the right ones.

But I never thought of using Sikaflex 4200. Thats a good idea.

I use 3M 4200 sealant from a tube on my sailboat. I apply it around all
the screw holes and under fitting edges.

AH!

3M again. I really hadent heard of it by the name Chuck used.

I've also been looking at sources for rub rail repair. water could be
leaking behind it, between the hull and the cap. I've been looking
through some archives and reading about the rub rail, This has some
gouges in it, but I've seen like the screw heads are pushing out
against the rubber insert. making a "bump" about every 4 inch's or so.

hmmmm.

A number of owners with Sandpiper 565 sailboats have removed the teak
rubrail by drilling out the plugs and then removing the screws. After
re-finishing the wood they re-attach using 3M 4200to seal the screw
holes between the rail & fiberglass hull and along the under edges.
Lastly, they use new teak plugs to hide the recessed screws.
I will probably do this job in the spring.

Sikaflex and 4200 are two different products. But either should work.

Both are polysulfide. Polysulfide come in a variety of flavours,
including household bathroom sealer. UV protection is desirable.
Paintability depends. Discoloration is a factor. Abhor silicone!
