Al's Gritty Mix - A-1 Grit Size
I just found a thread on making Al's Gritty Mix. I'm calling around getting my supplies together. As far as the "#5" grit from A-1, I found someone that says that they have a 4/5 blend in stock. I believe he said the #4 is a 3/8". Will that do or should I hold out for the #5?
