I use a muslin stacked wheel with white compound.
I recommend approaching buffing with great caution for safety reasons, of course, but also, it's my belief, you can rely on it too much and buff too early in the process, which will not look good. Buff in moderation. I dont buff very much at all and when I do, I'm choosy about it.
You might look into the Kratex wheels for some things. I love them. Same issues as buffing. Just be careful and learn when to do it and when not. Lin
