Is there anyway to remove sky marks from the crown of your driver? Thanks

Depends how bad they are... and what the crown is made of, finish, etc.

If the skymark isn't too severe you can sometimes buff out the mark with an auto body buffing compound then wax the head and buff to restore the shine. If the scratches are too deep you are kind of out of luck unless you want to send the club off to a shop that specializes in club head refinishing.

If there are really bad scratches (like down to metal or close to it) and you just want to play the club without it being butt-ugly, you can fill in the scrathes with a black Sharpie. It won't match exactly but it will get rid of the large color difference in the scratches and make them not very noticeable.

There's also a "shop" on eBay that sells exact color-match paints for OEM woods. If your driver is an OEM, you should be able to get the paint. Search them out.
Doing the fill, and making it look right is another story... And that's if it's all metal. If it has a carbon-fibre crown, you're out of luck if it's into the carbon-fibre.

And after you follow all of that advice, quit putting the silly marks there to begin with!!!

The Sharpie thing works really well and you won't be able to notice. I had a TM Rescue TP that had the paint chipped on the sole. An old black Sharpie made it look like new from 12+ inches away.

Automotive polishing compound should get the marks out, If not, move up to Rubbing compound, it's coarser. Most of these marks are just on top of the paint, so you should be able to polish them out.
