There are products by both Aurora Island Girl and Woodie Wax that may help.

Is there a way to protect rough, non-skid areas of fiberglass decks from
oxidation and UV? I'm assuming that these areas can't be waxed in the
same
way that smooth fiberglass/gelcoat can, or am I wrong?

Thanks for any responses,
