Yeah, Meguiars G110V2 is a good D/A Buffer from what I have heard and read. Griots Garage 6" D/A is what I own, and is also a great buffer. I don't think you'd go wrong purchasing either of them.
Also how do I keep from adding swirls or burnig my paint or plastic parts on the car ?
I am really nervous to take clay or a buffer for fear of damaging the clear coat and/or paint this car is only 2 weeks old... I am new to using a buffer and like I say I tried to wax an older car of mine (dodge stratus) with a buffer and liquid wax and it swirled and ruined the finish.
Well, to prevent swirls, you would want to make sure not only the surface you are going to use the D/A on is debris free (clean), but that your pad you are using is clean and debris free as well. To prevent burning of the paint, don't "park" the D/A in any one spot on the paint. Always keep it moving (by moving I mean with your arms) at a really slow speed at least.
Do NOT be nervous! I was in the same boat as you last fall. My dad was even more worried than I was. I took the "chance" and bought the GG6 D/A. I read all the articles on this site, watched videos, and applied everything I learned to my first use of the D/A. It took me probably around a couple hours to really get a good technique down. I'll quickly mention a couple key things that really improved my technique quickly:
1) Proper amount of compound or polish on the pad.
2) Drawing a black line on the back of the pad so you can see it spinning is probably one of THE biggest things a rookie can do to help themselves. Heck, I still do this!
3) Just knowing how the D/A is going to react when you come up to a curve on the body. After a while, you'll just kinda move the D/A flawlessly over any curve in the body.
4) The people on this forum are here to help!! When I was compounding my truck to remove swirls, I got on here and asked why I was having such trouble removing swirls. Even after 6-8 passes, I still had a decent amount of swirls. I was getting really discouraged. The members on here gave me several tips. I went back at it and within 10-15 minutes I was "mastering" what they told me to do, and I was finally making great progress!
Also, remember than a D/A from Griots or Meguiars is of a lot higher quality and much more designed for use on a car than your buffer at Sears is.
As long as you read up on how to use a D/A, watch a video or two, see how to "prime the pad", clean the pad on the fly, add just a small drop or two every pass or so, and you are at least decent with power tools, I know that you will have no issue using a D/A at all. Again, if something isn't going like you thought, stop, and come on here and I guarantee someone here will be able to get you back on track and on your way to flawless results.
A D/A is the best purchase I've ever made in the detailing world. I can't believe I was scared for all these years.
