[QUOTE="ben2go, post: 90256, member: 751"] If foam gets wet it will stay wet and absorb the water.Almost all foam will do it over time.Using a thick coat of polyurethane water seal on polyurethane foam will slow down the soaking up of water.Another thing that I have seen done is a thick plastic laid in the hold,filled with expanding foam,and then sealed with something like 3M 5200 marine sealant.I wouldn't put fresh wood over wet foam.It will rot faster and get infested with mold and mildew,and spread to the carpet and seats.
