Hi all, I have a relatively simple question, which compound is more coarse- Griot's Machine Polish 1 or Blue Magic TR-3. I need a pretty coarse compound for my paint. Is there anything thats more coarse than these that I can use with a random orbital buffer or my hand? I stripped a bad coat of paint off of the og paint of my 58 panel with 300 grit on a random orbital sander and am now moving up the grits of wet sanding and getting good results but would love something a little coarser than Griot's machine polish 1.

What grit of scratches are you going to try to buff out?

Getting out 2000 grit scratches you should barely even need compound. Ive never used Griots, but I had a look and #1 seems to be pretty course. It says its designed to be used on a random orbital polisher. Are you using one of those?

Currently, yes. Its one of the older ones they sold.

Go to autogeek.net and check out the store and the forums.

What random orbital do you have and what pads?

I have found the random orbit is happier polishing 3000 grit scratches than 2000. And thats with a forced rotation random orbit. A rotary would buff out 1500 scratches. So I would either sand it with 3000, or find a rotary buffer.
