Make sure you aren't using too much product and make sure to work it long enough.

The sfx line is a diminishing abrasive as far as I know, so I haven't really done much priming of the pad.

I've learned that 6" pads are kind of useless, so I'll get 4 inch next time. I also think that I'll get the menzerna SIP when I'm out of sfx.

Btw, my friend Rob Bogdanowitz praised your work greatly Scott (he's got the blue 335i and white X5), so keep up the good work.

, in addition, running the PC on 6 and applying pressure will work the PC so hard that it heats up and the heat goes down the shaft and into the backing plate, so that the backing plate eventually fails. I've pretty much given up using my 6" cutting pad for correction, in favor of the 4". I still use 6" for final polishing where I don't go above speed 6.

I have had plenty of success with a UDM and SFX1 polish and SFX1 pads. Infact the yellow pad is my favorite pad in the bunch. It works really well with the KBM method and would suggest everyone try it atleast once with the Sonus yellow pad. This pad is so freaken versatile it is amazing.

But I think you just need to practice and try different ways untill you get it down. Also, you havent explained how deep the scratches are and even if they are correctible. But keep trying. SFX1 polish is pretty strong stuff (plus it smells great) and with the 6 inch yellow pad there are a lot of corrections that can be had.

This isn't a I am better than you post. I jsut don't want you to get discouraged and think you can not achieve the desired results. Because it can. Stick with it

You guys are right, and after finishing up the benz, i have to say the results ARE impressive. Still some rids and some very slight swirling, but the designo black metallic sure looks great. I topped with megs 26, and am now scared to touch it.

As for the mustang, I think it was the result of not working the product nearly enough, and having incorrect expectations.

I'll have to give it another whirl, although the 4 inch pads probably would work better.
