Hi,
I would try wiping the area with a paper towel soaked with acetone. Wear gloves and do in a ventilated area.
If that doesn't work, I think it will, try a scuff pad. don't use a lot of pressure.
If you scuff pad the entire blank, clean with isopropyl alcohol 91% and paper towel, then you can apply a thin coat of finish epoxy.
However, I would install the wraps and guides before epoxying the blank area.
If a problem arises get me on the land line.
I think it will come out just fine.
