Buffing Streaks

I don't like the DA'S not enough heat but they are great for feather edging !!

Your not trying the right D/A the Rupes have more then enough power.

I havent touched my Dewalt in 2 years. I would still use it if I were buffing after wet sanding fresh paint but I would never finish with it. I also cant stand 8" pads though. I prefer 5.5" foam.
