I'm surprised about that and haven't noticed it on ours, although I only have it in a foot well and never really remove it much to check. By holes in the fiberglass
, do you really mean just the gelcoat
? Even then, I would have expected the rubber-like dri-dek to be softer than the gelcoat
. One possibility is that small, frequent slight movement might be slowly grinding away the gelcoat where the little nubs contact it.
