Our Manufacturing folks use a basic epoxy to protect any exposed copper created in the rework process, from cutting traces or intentionally removing solder mask to add a part. Any clear, two-part epoxy should work fine.
If you want to hide the scratch, you may be able to use some green paint over the epoxy.
