Looks like pretty fresh cut normally we let dry year or two.At least get the moister content below 12%.There are guys on here that are experts if they see the post they will help.There is quite a bit to it.
It would be better if you sent it off and had it stabilized,but if you don't after your done removing all(all) scratches.Put a thin layer of super clue on it,sand very lightly.and do this process 5 or 6 times.
This works ok ,but you have to be careful when cleaning(if its a user) .never put acetone on it or anything harsh just soap and water.
