I vote that you do nothing and wait. I think that the dimples will eventually fade away.
Any proactive measure could go awry and cause permanent damage?

I saw your RV-4 at Reno. Very nice. The prop was very interesting too.
Congrats on the Rookie of the Year award!
My first year at Reno, this could be habit forming. I see that being a spectator has limits. It seems best to be associated with a plane.
