Can you post a photo of your boat and what you are trying to paint ??
Almost all good paint stores nowadays have a computer
to match any color you bring into them. It only takes a 1/4" square of color to sample.
if you can find something removable, even a bolt or washer,
that you can take to them, they can match it.
I am going to ACE Hardware this afternoon with that same issue. I need ext. oil paint.
It is an old Benjamin Moore light teal green color that is no longer made.
I have their color swatch book that is from the early '80s and is extinct.
Sort of like the original '57 Chevy light turquoise color.
Can you pull your boat to a paint store? maybe they will allow you to take their
color book to the parking lot to match your paint. (when worse comes to worse).
Last option would be to repaint your whole boat - then - you will have no problems
in the future with finding the correct paint.
good luck.
oh, and as for the MDO, the flat surfaces are just about bullet proof and impervious
to water. it is the edges that will allow water to wick into the board. So it is of the
utmost importance to seal the edges and all the holes you put in it the best you can.
My good friend, Butch Anton, wrote this article a long time ago - but the information is still current.

The procedures will be the same for boat bench seats or a transom.......
