I'd do the seats to match the deck. Then the scoop done to match the sides. IMO when the seats (2) start getting to wild it tends to take away from the rest of the boat. Leaving them white looks like.....#1. Painter was to lazy to do them
#2. Couldn't come up with an idea.
#3. Ran out of cash.
Now I know your doing them so # 1 & 3 don't apply here.
