6 comments on Preferred Pattern When Polishing by Machine

  1. Jon says:

    Nice one, Ivan! So, tell me, do you consider (1) left-right + (1) up-down = (1) ‘Section Pass’, or do you consider each direction pass equivalent to one ‘section pass’. Speaking of which, how many section passes would you do in this particular example (M205 + Crimson LC flat pad)?

    Thank you,

      Thanks Jon,

      (1) + (1) in this case does equal (2) :)

      What I mean is that (1) left to right is (1) section pass and (1) up and down is a 2nd section pass. I don’t count the initial spreading at a slower speed as a pass.

      As for how many passes, I typically do anywhere from 6-9 passes with Crimson/M205 but there are way too many variables for me to tell you how many you would require. I would recommend just trying out different techniques and pressure/speed until you find the best combination. This is especially easy and helpful if you are working on a personal car in that you can tape off many different sections on different panels, then try out different techniques. You can try only 5-6 passes and vary the pressure, then step up the passes while keeping the pressure the same, etc.

      Hope that helps!

    Good info. One question…that seems like an awful lot of polish you are working with. Did you use extra polish just for this demo so u could see the polishing pattern better or do you always use that much when usong 205??

    • Ivan Rajic Ivan Rajic says:

      Good eye Dan! You are correct that I used extra polish (basically primed the pad twice!) for this demo so it comes up clearly in the photos. I normally wouldn’t use nearly as much.

    Oh My Gosh! I am stuck with a car that has such an oxidation coating I am a bit confused. I have been around automotive finishes, use of buffers etc. However, the daunting task of the whole car is not my idea of a fun weekend or more… And just how many buffing pads am I going to need? I just want to get the finish half way decent so I can sell the vehicle…

    • Ivan Rajic Ivan Rajic says:

      Hi Diane,

      It’s very tough to estimate the amount of pads you’ll need not knowing the car type as well as how bad of a condition you need to fix. Normally for any decent polishing to be done, you’ll need about 6-8 pads at least to complete a polishing step around the car, probably more if it’s oxidized and the pads will get saturated very quickly. That or you can do it in sections over the course of a few days, in which case you can wash and dry the pads after each day. Hope that helps and best of luck with the project!
