Refinishing slate/glass calls?
I have had a glass/slate combo call for about a year now. It used to make a good sound when I first bought it. Now, it screeches and sometimes doesn't even make a sound. The striker is practically smooth. I tried sanding it down but that only works for a very short time. I was wondering what i could do to fix this. I don't want to take a call in the woods that I can't depend on.
