    Was this panel very dull and oxidized looking before you started?
    I second this.

    Agree with what was said above.

    Looks like what a dried and oxidized single stage paint would do if you tried to buff out at first round.

    Re: Marks after polishing

    Ok let me explain. The paint is VW LC9Z. The car was repainted year ago. My goal was to remove mini scratches visible under direct sunlight. I have a lot of mini scratches from automatic wash. From what I see new paint is very soft compared to OEM VW paint.

    I'm using oribtal polisher. Yes, I wrote RPM but I meant speed. What speed I should use? On the polisher there are only steps from 1 to 6 if IIRC. I think I made mistake by putting too much pressure to machine.

    I told you what to do above. Set it on three with a medium pad.

    I really doubt that's it. The DA will stop spinning if you put too much pressure on it.

    It's really hard to do damage with a DA. Unless the paint already has some defect like clear coat failure.
