I ran into this same situation myself just a few days ago. I luckily had a roll of 3M invisible shield sitting around because I pretty much 3M everything I own. I do it because like to use my gear the way it was meant to be used and not worry about wear and tear that goes along with using it that way. Then when it's time to sell, I just peal it off; good as new.
Look on eBay for rolls of invisible shield, then just cut the shape you need. It's cheap and works beautifully.
