The boats a 2004 XLV and the swim step pad seems to be breaking down. At least that is what I think is happening. No matter how much I clean it, once we hit the water it leaves a black residue on your feet and hands. This is not cool for the white interior. Anybody found a way to stop this or has had this problem? If I have to buy a seadek pad I will but at the moment it doesn't look bad, it just is acting bad. Thanks in advance.
