On my '08 Sunsport in the front center ballast bag locker there is a rubber mat they put in to go under the fat sac. Has anyone removed this and not used it? I cleaned it out again today and it is developing this white, pasty residue under it. I just completely cleaned the entire locker a month ago and it is already returning. I always air it out and open the locker after we are done using the boat. I cant see why it would be a problem to just lay the fat sac on the fiberglass flooring, anyone doing this? and is anyone else getting this type of white pasty residue in there locker?
