  • First time using the G100. Take a look!

    Hello folks!
    I just got my G100 / PC and begun to do some tests on my car.My car was swirl city after an improper QD'ing after driving on a VERY dusty road.

    First of all now I understand why is it so hard to explain over a keyboard just how much pressure to use. Basically is a matter of judgement and common sense. Once you start working with it, you can get a feel for how much is really needed.

    The first thing I did was to mask out a portion on the trunk lid, then I primed my brand new polishing pad with an "X" of M80 Speed Glaze, then put the PC cord over my shoulder and set the pad flat on the lid, turned it on at a slow speed, and gradually increased the speed up tp 5 OPM's. Then I worked the product in overlapping sweeps, left to right, up pand down making sure to move the PC slowly. Stopped when the M80 was almost invisible, but not dry. Wiped with a Supreme Shine microfiber. I repeated this 3 times. And got this.





    Felt pretty good about myself, being my first time with aPC and all.

    Then I decided to move over to different areas of the car, and do some more tests.
    So I moved to the front fender. I used the same procedure.
    Look:



    I didn't tape this one, but as you can see, it looks pretty good.

    But after looking at the fender from different angles I found this:



    If you look at the fender at a certain angle, you can see some swirling or micromarring.

    I'm pretty sure that the MF was clean when I removed the remaining product. Also I used another MF to clean off the excess buildup in the polishing pad.

    But upon closer examination I found this on my pad (look at the edges)



    I'm pretty sure this is what caused the marring. Like I said I cleaned the excess on the pads every 2-3 applications. I think I'm not over saturating the pad, as there was no product transfer onto the velcro side.

    Should I clean the pad with a toothbrush every 2-3 applications?

    Well folks, that's about it. Sorry for the long post. Any tips or comments are welcomed.

    The only way this machine would cause swirls would be if the pad is dirty. A tooth brush doesnt work to well to clean because of the way the machine spins. The toothbrush method works grealy with Rotary only. So it's definitely a great idea to clean the pad in between applications. This also helps the pad regain some cutting power. If the pad is heavly saturated this lubritates the pad to well loosing it's abilty to cut. So periodcally clean the pad by pressing a cotton terry towel onto the pad to absorb any excess product or have another clean pad ready to go and switch. This my be a reason my the fender ended up looking like this.

      Gracias Jorge!

      What I do now is spray a little QD, then I use a towel to absorb the excess.

        I have the same problem. I use a spray of QD on my pad before each product application, I try to keep the pad moist. Then I'll use a blunt object and occasionally scrape the outer edges of the pad to remove anything that hangs off.

          I have just done the same thing to my car!
          I have tried #83, #80, #7, Yellow pads, orange pads
          Green pads, White pads, with every combo...
          The micro-marring is still there!
          Is this HARD paint ? (Mercedes,black)
          Soft?
          The best results I have had at looseing any of these
          has been with MPPC and a white pad (softest)
          What is going on??
          I have spent $$ and 9 hours on the trunk lid alone,
          With basic-ly NO CHANGE in the finish.

          Any and all help would be apperacated.

          Thanks, Kevin

            blkhole,

            If you have been buffing for 9 hours with no progress, you need to try to find something more aggressive. Always start with the least aggressive product and work from there.

            I just did an 01' red explorer with similar marks on the hood and they would not come out with 1500 grit compound or 83 with the DA. I had to use a rotary buffer with a wool pad with 800grit compound, then 1500, then 83, 80, then NXT to get it right.

                  This chart can pretty much be summed up to 2 speeds.

                  Speed 5 for removing defects with a W8006 pad and removing wax with a W7006 and a MF bonnet

                  Speed 3 for applying a pure polish/wax (LSP) using a W9006 pad.

                    What year is this black Mercedes? I've worked on many, and had to use a rotary buffer to restore them.

                      when i first started to use the g100, i put too much product on the pad thus saturating it, and causing it not to have any cutting power. now i use a mf towel/terry towel and press into the pad to soak up any product if i notice there is too much on it in between every few applications if necessary...

                      p.s. if anyone ever has a question or needs info, JORGE IS THE MAN!

                        OctaneGuy,
                        The Benz is a '98.
                        I have cleared a section useing Scratch X and then went
                        back over it to see if I am putting these in.
                        And I am getting marring useing a white pad! (brand new no velcro bits)
                        the stiffer pads just make it worse.
                        Don't get me wrong the car looks great except
                        for the micro marring and cobwebs. they would have to be pointed out to most people.
                        Two years ago I had done the whole car by hand with Scratch X,
                        #7, and sealed with # 20. Topped with #26.
                        The car had none of the little scratches.
                        Not wanting to do all this work by hand I bought a Cyclo.
                        And $100.+ worth of Differant "polishes" just to make the job "Easy-er"and do it more often. $350.00 later I find I am worse off than if I had just kept up the hand work.
                        Thanks for letting me rant.

                          OctaneGuy,
                          I have been thinking of trying the terry cloth bonnet,
                          with my last polish, What would you think of that move?
                          (to apply not remove)

                            I never tried using a bonnet to apply polish. For me, once I'm using MF on my paint, terry cloth seems backwards, since I'm looking to have my finish taken to its maximum potential, as Mike calls it.

                            I've worked on a lot of black Mercedes paints from as old as 1992 to 2005. In all the cases, I was able to remove the swirls using my Makita rotary with a W8006 or W9006 pad. In some cases I used a W7006 pad to remove deep scratches. I then finished with the PC.

                            Even for the 1992 paint, a PC was able to pull out the scratches using M83, but I opted for the Rotary since there were numerous defects to be pulled.

                            Seems you are using a variety of pads here.

                            Have you just tried a consistent sequence with new pads
                            W8006 pad with M80
                            W8006 pad with M82
                            W9006 pad with M21 or NXT Tech Wax?

                              Yes I have tried a sequence of cutters and pads
                              in just about every possable combo.
                              Maybe if there was someone on the forum around
                              here they could look at it and tell me what is going wrong.
                              Thanks, Kevin

                              There are no 4" meguiar pads around here, I am useing
                              the Cyclo pads that came with.
