I think mine are teak also. At least the areas where the paint is peeling away.
My doors are in good shape. The sliders have some wear, but not much of a change since we have owned her the last 2 years. The more I think about it, I’m thinking definitely teak for the sliders. I’ve had one door off and it was heavy, so I think it’s teak.
Wish I could say the same for the cabinet doors on the fly bridge.
