A thought on Sikaflex - it's used in conventional
boatbuilding and is a bear to remove.
Have you considered making your own O-rings?
You can get it in many diameters. Comes in rolls. I believe you
heat up both ends (of any length) and join them together. Lay down
two or three O-rings of any shape but make sure to offset the
joins.

You know what might have happened Emile is that it might
have been too cold when I installed it. After all, it is called ROOM
TEMPERATURE vulvanization. Just speculating, I don't really know why it stayed
liquid.

RTV isnt that bad. I
have good results with peppers dome (210 meter!) . Fix and
forget. Does not stay liquid.

Good luck Vance. The
quick and dirty seems right for my small viewports. Don't
foresee
any removal in the
near future. Besides I have always enjoyed destruction

Yeah,
understood. The point to RTV for George was that it serves both as gasket
and sealant, ie., quick and dirty, and it works. Not fun later, as I said,
but it's great stuff. I was thinking of cutting thin red rubber gaskets
(1/8" thickness) then using a thin coating of RTV on both sides. That would
give me the soft barrier and less vulcanized goo down the road. Wish me
luck

That is what I
have heard about RTV. So I am assuming then you would
use
Sikaflex. It
sounds right but there about 400 different versions. Hard on a poor
old

I haven't looked
into it. Mine were bedded in RTV, which sealed effectively, but were
not what I'd call great fun to get out again for paint, etc. Sikaflex
doesn't cure the same way, and never takes a set. RTV is, of course, the
acronym for room temperature vulcanizing, and they ain't kidding. It bonds
and sets up something fierce. The other problem with it is that RTV can't
be repaired. It won't bond chemically to itself once the original
application kicks. Meaning that if you have a leaker, you get to try out
the car jack again to break the port loose (and hope that the RTV is the
ONLY thing that breaks). In either case, you have to start scraping and go
back to square one. What a pain. Trust me, there will never be
another submarine in my garage with goop sealed ports.
Never.
