I want to buy some of this polishing compound as i hear lots of you use it for restoration. I have a Dremel and picked up some buffing pads for it. Thinking ill need to buy better ones as these are thin little cotton pads.

Anyway, i was at Harbor Freight the other day and seen they have 3 different color clay like polishing compounds. Has anyone used these? Are they worth buying? Or should i just buy the huge bags (3lbs) of the stuff? The H.F. stuff dont list grits.

And if i was to buy the real deal stuff, what grits should i be buying? I hope to buy a real bench buffer in the future but id rather have one that is both buffer and grinder. And i guess i need a variable speed? Well, this is in the future. Right now im wondering about the compounds. Thanks for any help.
