Brush time?

[wisconsinteacher]

When polishing a barrel, how long do you use the same brush.  After 200 passes tonight, I am going to put on a new one because the first one is bent over a lot.  How long do you use yours before replacing?

As cheap as they are, it really doesn't hurt to change them out once they become wore.

I can usually get thru one barrel before changing brushes.
