Scratches are common. Grease will just make for a mess when you remove it.
Everytime you pull the trailer you will have to clean the ball or get grease
all over you everytime you bump it.

I'm about to tow my 24 ft I/O (5,000+ lbs) from NY to Florida with a
newly purchased trailer. In the process of shaking everything down in
advance, I've noticed that the hitch ball is getting scratched up
quite a bit. Question 1, is this normal or should I be concerned?
Question 2, would it make sense to pre-lube the hitch ball with a
light coat of grease or is that a bad idea?
