Re: help me with my hull to deck joint!!
You do NOT want to put fiberglass insulation (pink panther) up into the space behind your valance or "crown moulding". It will soak up moisture and turn into a mold-generating, rot-spreading wick of horrible proportions. If you have to insulate, use a closed-cell foam of some type (the blue styrofoam, for example) that doesn't absorb moisture and which can be shaped to a close fit. Remember that you may need to get at the hull-deck joint again later - perhaps to track a leak or re-bed a stanchion - so don't glue stuff in there either. Perhaps you can put a screw through the valance every here & there to hold the foam in place. If you don't like the color of the insulation you may be able to paint the side that shows. (Watch out- some paints will dissolve foam!) Looks like you have enough to keep you busy until August or September, anyway. Enjoy!
