Yeah he's using 6085 to cut with on a white pad. 6060 is a more aggressive compound to use for something what your doing. The problem is 6060 was discontinued and 6085 took its place. It is still possible to get 6060 but its hard to find. OAK has M105 & M205, they are a distributor.
The buffer he was using is an older one, and my guess (as Ive talked with him also) is the buffer was just old and wore out.
I would have to say, now seeing your pictures, if that compound and that pad is not "cutting it" like Andy said, your gonna have to get out some wet paper.
Your are making progress for sure. The pics are telling us that. Here is something that may help you... From the looks of your pictures I can still see the residue from the compound (thats a good thing). If you have a microfiber towel (clean) wipe the residue off the panel as you go to really see your results.
And like Andy stated also, if you pull it outside and it looks like shit, your doing something right! That compound is going to leave holograms. Thats why you got the black pad. What polishing glaze did you get? Or did you have some? Using the Zaino for that?
Just another tip, dont mix pads and compound.
