I don't get the blue Rupe's pad either. They seem to scour the finish on most all but the hardest paint (ie. German cars). Forget about using them on Japanese paints. I gave up trying to use the blue 5.5" pad. Recently got a Mini kit and I'm getting the same results with the 100mm blue pad. I kept trying to make the best of these pads thinking that maybe they needed a break-in period, but they behave the same as when new. I also got Rupe's blue pads that are made from different foam. One has smaller pores but is stiffer and has different screen printing on the Velcro backing. Didn't know they changed their pad foams already.
SO are these supposed to finish out well?
I get along with the green and yellow pads fine, but so far I do not see what makes these pads such high quality to some people. I have had much better results from the Griot's and the new B&S HD pads. I hope B&S comes out with 100mm HD pads soon.
