The drips on the floor probably leveled themselves out to where they are about the thickness of what you might put on your boat. If the spots on your floor are green, and you can trace the color to the epoxy alone ( no one mixed any extra pigments or colorants in) then you can assume that for the typical thickness used on boats, the epoxy will make everything look green.

If you want a green boat, which might be very practical for St. Patricks day, then go for it.

Otherwise, I'd save this stuff for areas where it won't be easily seen, or where it will be painted over.

Just an opinion.
