Did a Sigma...
Did a Sigma, it was easy, took about 4 hours. #200, 400, 600, 800, 1000, 1200, 1500, 2000, 2500 grit wet-sand and some Mothers mag polish. The most important thing is to get all the "scratches" from the previous grit out before moving up. My Nephew said it was like putting rims on a Yugo. I got 20 crack rocks, an ounce of weed and two crack ho's for two hours for it down in the ghetto!
