ILD: Been using the Makita for around 3 years already.. started off practicing with old beat-up cars. then finally mustered the courage para sa ride ko...hehehe the idea of using one was daunting at first pero once you get over that initial hump you'll be blown away by the results. Also, some painters in our warehouse were willing to help me out...

IMO, The best ways to learn are:
1) actually use this tool (just pick it and let her rip...hehehe)
2) learn from watching / have someone teach you

hmm as for tips, hope other Rotary users can chime in pero here's a few:
- keep it moving at a constant Left to Right / Cross-Hatch pattern; don't stay too long on one spot
- don't use too much pressure
- use the right pad-product combo (depende na rin sa skill level...)
- make sure you have a complete grip on the Rotary

will try to post a few more later...
