Traditionally deck seam would be filled with a seam compound or a marine sealant such as Sixaflex or one of the 3M fillers.

But if this is for the foredeck of your Thompson Runabout and you intend to varnish it you might have problems getting the varnish to stick to any of theses sealants.

On approach is to use pigmented epoxy to fill the seams.

Mask off the surface of the planks so epoxy only goes in the seam.

Get an empty caulking tube to feed the epoxy with.

Then mix some white pigment and a bit of silica thickener into the epoxy, and pump it into the groves.
