    Not strong enough?

    I was working on my dark blue Lexus GS300.
    Started with doing a test spot.
    Using G220 w/ Polishing Pad w/ Ultimate Compound.

    First Round...
    3 passes on with about 9kg of pressure
    Only some very fine swirls removed.

    Second Round...
    Add some more UC.
    Again 3 passes with >9kg of pressure
    Not noticeable result from the first round.

    So I gave up since I don't have anything stronger yet.

    I'm thinking of getting a Cutting pad?
    I heard that cutting pads are not for D/A.

    Or getting M105 and work on the same polishing pad.

    Which choice should I made?

    Thanks

    Re: Not strong enough?

    Your pressure of 9 kg (about 19 lbs) sounds about right, but your passes sounds like it might not be enough. Also, are you conducting passes in one direction, or are you using an overlapping crosshatch pattern (preferred). ^ passes in this pattern is a good starting point, but really just work the polish until it's appears very thin and filmy.

    Also, you don't mention the speed of your passes, but try moving your G220 at a rate of 5 cm per second.

      BTW I was on speed 5.
      Running on G220 w/ Polishing Pad on

      How many passes do I need??
      Just polish until the chemical all gone from the surface?

      BTW Can I use UC and M105 on a same polishing pad?
      Need any extra cleaning?

        I was actually going to say that 9kg sounds a bit heavy. Are you sure your pad was still spinning? Also, as ClearlyCoated mentioned, your arm speed could be a contibuting factor.

        Just clean any excess product from your pad using a terry towel and/or brush and you should be ok to change from UC to 105, as they are similar types of products.

The silver one demands nothing and it looks just fine. I think the black vehicle is taking advantage of me, and the silver car is more my style. We can go out for a drive without her makeup and she looks fine. If I want to take the black one out, it is three or four hours in the "bathroom" to get ready.

          Ive never mixed products on the same pad, and i actually dont think is healthy in my opinion.

          What year is your GS300? Modern clearcoats needs arround 4 to 6 passes to see a difference. Dont apply so much pressure it wont cut more if you put more pressure.

          Here is a post on how to work it out with the DA, what are peoples most common mistakes on the DA. Give it a try with this tips. and let me know.

            Re: Not strong enough?

            It's about 10 years old already.
            I think I know what I was doing wrong,
            I probably uses too much pressure onto it and I was didn't
            observe the rotation of the pad.

            Could this be the problem?

            BTW Can I go with cutting pad?

            Anyway I just ordered M105 and M205 to work with on my Polishing pad.
            Will this be the solution for me, getting the bottles next week.

              A lot of times the problem is the that the pad does not rotates because of the pressure your putting to it.

              You dont really need to go with a cutting pad.

              And i bet you the 105 and 205 will work great on your paint. Just work it long enough.

                Ok, thanks Ryan
                I'll start working again as soon as those 105 and 205 arrive.
                I heard that 105 and UC are pretty much the same....
                So afraid that 105 wont do much cut on polishing pad either

                  sobhark, it sure sounds like the problem is that the pad was not rotating; as a result you did not get abrasive cut that you should have. Mike Phillips suggests that you draw a hash mark on the backing plate and/or pad to enable one to see the pad rotating: Check out this article. I would try the Ultimate Compound again but this time make sure that the pad is rotating. You want to apply pressure but just not enough to stop the rotation of the pad. Bear down on it to make the pad stop and then let up a bit to allow it to start rotating again--that is the amount of pressure you want to apply.

                    You may also want to prime the polishing pad with the Ultimate Compound (or M105, if that's what you are using): A Look Into Pad Priming. After you have primed the pad, you only need to add 3 or 4 dots of polish per section. You don't want to use too my polish, just enough.

                      Try a yellow buffing pad. Stay away from the burgandy cutting pad. I found using a polish (tan) pad did next to nothing when trying to remove defects.

                          Are you using Meguiar's pads? If yes, then you want to go with the yellow polishing pad. If no, who is the manufacturer of your pads?

                            Yes I did mark the pad.
                            But what rotating speed are we looking for?
                            If no pressure, just the weight of machine, it spins pretty well.
                            Moderate pressure, then it spin like 0.5 rpm

                              I'm curious too. Apparently the ammount of product influences the RPM. Too much of the product wil reduce spinning.
