Yes, you can apply TotalBoat Wood Honey over cured epoxy. Be sure to remove any amine blush from the epoxy and dry the surface completely before applying Wood Honey. It's also a good idea to do a test sample to ensure you achieve the results you're looking for.
You can also use Wood Honey as a friction polish for turning and buffing projects using epoxy.
Keep in mind that applying Wood Honey to a cured epoxy surface still has limitations as far as certain food contact and food-safe uses are concerned.
