Another way is to have the ski wrapped - new custom set of decals.

Do a search on eBay - you will find a host of vendors that offer wraps for the exact ski you have.

Of course I'm not sure what state the ski is in but in some cases this gives an appearance of better than new given the custom looks you can get

Good luck and send us some before and after shots independent of your direction
