I am not sure - HK costs a fortune - I'll bet that if U can, you would have to pay a fortune. I'll bet $300. U need to call HK directly, though.
if U ONLY wanted the other finish, you could send the slide into a company that does the refinishing work for HK, and they could do it for you.
I am not home right now otherwise I would post the link. I think I have it saved.
