: John,
: For a bedding compound you're better off with a marine sealant. 3M has a good
: line in white and black. Stay away from their 5200 if you may ever want to
: remove the fixture. Like anything with "marine" connected to it
: these products aren't cheap, but are gnerally available. I have found some
: at my local "Big Lots" store were they go for a buck for a tube
: good for a job like your's.
: Good lick.

I got my black silicone at Lowes yesterday and have the deck plates installed. But "Big Lots" is one of my favorite bargan stores. I hooked a wire to a nail and my router to cut out the circle for the plates. The side compartments are all fabricated and I will start installing them today. To answer one of the other responses, these plates don't have any O rings, it's more like a pipe thread that seals them water tight.
