The tops of my horizontal boat compartments that are on the floor and the vertical/side compartments on my aluminum Tracker boat have a black styrofoam type of structure on the that are starting to disintegrate. Has anyone replaced the tops of these compartments with anything or applied anything to them to prevent them from disintegrating into those little crystals? Mainly care about top of live well and bait bucket as it leaves tiny black pieces and residue in them. Thanks.
