Cabin insulation and Mascoat Marine DTM

[Cal28]

As I am more or less a live-aboard on my Cal 28, it's time to add some further decor and insulation to the cabin. I have an abundance of beautiful mahogany in the main cabin, and although I initially rejected the idea of painting the 20 or so sq ft of bare space, I have now come to realize that it might indeed brighten things up and even add to the natural wood's appearance. Before I start, I would also like to address further insulation for the winter (which to me is all year round here on San Francisco Bay - save for about a week in September - which is why the America's Cup is scheduled for then I imagine).

I came upon the following ... Mascoat Marine DTM ... as a possibly solution for an undercoating and wonder if anyone has any experience or thoughts on it's potential use.

As always, thanks for any and all input.

It might stop some condensation, especially on the steel and aluminum hulls that it is designed for, but it will not insulate more than the same thickness of any other insulation as far as heat loss is concerned. It is not designed for that. I would suggest 1/2" closed cell foam glued to the hull/cabin interior where it is exposed and in lockers as well to stop condensation and the resulting damage to items stored there. Cover it with plywood panels or ceiling strips where it is visible.
