Hey guys. Fairly new to the site and I have learned so much just reading. Thanks to you all I have started making some $ with my trusty PC on the weekends.. I do have a job lined up this weekend involving aluminum polishing (tanks & wheels on a big rig.) I do not own a Makita or a Dewalt but I do have a Milwaukee HD rotary one speed. My question is, where can I find the DW849 or the 9227c by Sat?My local Home Depot/Lowes does not have them. If I cannot find the 2 units, the Milwaukee should be just fine for the high speed aluminum polishing, correct? Thanks.
