    Thoughts or experiences using spray-in expanding foam on the interior hull scantlings? The Roamer I have been looking at, 55' aluminum, appears to have super clean interior hull sides in engine room and other under deck compartments, the silver paint, bitumastic I believe?, shows no corrosion or leak staining. Would there be more to gain in the areas of sound proofing and thermal insulation over the risk of covering internal corrosion? In all my readings I have not heard of interior corrosion in non wet bilge areas being an issue. Ultimately would like to paint the hull a nice deep navy blue which could cause for some serious sun/heat absorption, thus the idea of the poly-foam insulation to mitigate the heat.
