    cantex,

    On the flat stock that I polish I use a 6" DA, I start with about 220 Grit and finish up with 400 grit and then polish. If I have a lot of profile on the piece I'm polishing I will use a die grinder and cartridge rolls and then greaseless, then wet sand and buff. I also have a bench mounted disc/belt sander that comes in real handy!

    The 3" discs would be great for getting into small areas. The 3050 kit has a pretty high RPM so you will have to watch that real close. It will eat aluminum real quick!

    I don't see any advantage over my $20 air drill. I've never had it (or the mini die grinder) bog down at all unless the air gets in short supply, but I use the electric stuff more since my compressor ain't the biggest. It's real good to have both tho - in case one burns up you have a backup.

    I use a flex shaft & 1/3 hp motor for slow stuff, backed up by the air drill. My air grinder took a dump the other night so for high speed I have the electric die grinder.

After wrestling with my project for a few day I switched to an electric angle grinder with a 6" and 4" buff and have had good luck. However the angle grinder does have a very high RPM, and can pull you in (bit) if your not careful.

    I am just speaking from my quick learning experience.
    lowpsi your not such a newbie anymore, giving good advise. air grinders will work with alight touch but take a lot of air to run. i use both air and electric tools at times but more often than not i reach for the electric stuff, but i have a light duty compressor.
