Are you refering to a scale boat with a mahogany deck and all kinds of details or a racing style boat that you just want to keep from getting water logged? Basically, sealing is done with a 2 part epoxy like West Systems or System 3. It flows out well and can be spread with a squeege. Let it cure a day or two, sand it and apply more epoxy till the grain is full. If it's an electric powered scale boat, I'd use spar varnish.

Hmmm....

Well my plastic kit has an o-ring seal and is held down in 17 places with screws. Still I use a bit of petroleum Jelly to make it water tight.

Perhaps this may help you?

Mix a small amount (about 4 oz) epoxy, not the 5 minute junk. Add cabosil or other milled fiberglass product and stirr in until it as thick as peanut butter. turn the deck upside down. Fillet the corners of the inside of the deck with the above mixture, all the way around. Push the hull into position. Use masking tape to hold in position until cured.

You do this upside down so nothing can run down the sides of your hull. If the boat is ployester resin based you can use that instead of epoxy, just add the MEKP first, then the cabosil.

After the deck is joined you can fiberglass the joint on the inside with a peice of 1 1/2" wide fiberglass cloth. Use the resin of choice (No thickener this time) Put a 1" brush on the end of a little stick to reach in and wet out the glass. Some people wet it out first, roll it up then unroll it inside the hull using a sharpened dowell then use the brush to pat it down. Use a patting method with the brush, not brush strokes. this is important if you want it to look good.
