I just bought a Columbia 300 C/Beast or something on eBay. I just know it's one of the Urethane Beasts, well according to BBR.
Now, I realize that urethane and reactive resin equipment are completely different, but has anyone tried taking a urethane ball to say 2000 grit or even 4000 grit abralon?
I wonder how it would affect the reaction of the urethane ball....hmmm....
