... thank you for helping to prove my point.

Cleaning a chip to remove surface grime is not, in my opinion, "repairing" it. However, applying any substance to change the color would, IMO, be a "repair" -- see Merriam-Webster's definition:

>> b : to restore to a sound or healthy state : RENEW

All of which just goes to show exactly how slippery this subject is.
