Can it be used to coat a Rosewood fretless fingerboard? I have defretted my Ibanez SR 190 and put maple lines in it and well... It wasn't the best job in the world and the glue didnt get all the way in the slots and some of them have brken off and are beggining to break off (the ones who didnt get enough glue). I dont wanna go through lining it again so I've decided to go epoxy. I noticed the Stew Mac slow-setting black epoxy and I was wondering if it would be ok to use it on an unusually string rosewood fingerboard? Or should I use the clear one? Im not worried about seeing were the fret lines are as I pretty much know this basses neck like the back of my hand.
