Ahh, ok, I see that you have removed all masking tape therefore best to let it sit for a while before doing the final polish. Meanwhile you could lightly sand back with 1500 or 2000 wet & dry grit used dry where the Tru Oil has seeped onto edge of the rosewood fret board. Once tidied up suggest applying wax to all bare rosewood surfaces as this will help keep it waterproof for when you do the final wet sand and polishing stages.
