Most hull blisters are from water coming in from the outside and getting in the fibers in the glass and puckering out the gel coat causing the gel coat to blister. I could do it from the inside out I guess but the main troubles with wet foam is the extra weight that you are carrying in the hull. Water logged foam is heavy!
