I am reflooring a 72 GC CV-16. New 5/8 plywood and epoxy etc. The question is do I get any benefit from foaming under the floor. The area is only about 30 inches wide by 8 foot long by 4inches deep at the deepest point. It has one stringer down the middle. I don't think it had foam before or if it did somebody did a great job of cleaning it out. I really think everything is original and was suprised to find no foam. Any thoughts or opinions?<br /><br />Russ In Texas
