I had a knit headcover on my driver last season, and an alignment rod with no cap on it. I didn't think much of it until one day when i pulled off the headcover and the top of my driver head had a number of long scratches across it. Just wondering if you guys have any good ways to take care of these scratches? They're not very deep, and not too noticeable to most people, but they really bug me at address, which isn't very good.
