When you "scorch" the air, where does the H2O go?
I was about to ask that too! I find that it does work, my boat is drier with it, but the how is a mystery.
Also to poster re: air space, that is partially true, but having a cold surface and moist air is not great. I am insulating first, then bagging the foam, later hyper dry when i can find a Canadian source. (dry dek is too expensive for me right now).
For lockers inside it will be insulation only. For lockers outside hyper dry only.
