Re: Marks after polishing
Menzerna 2500 is a medium cut , you need to polish again with a fine cut. I use Meguires 205 but there are several finishing polishes in the Menzerna line if you want to stay in that family. If you choose to finish with an AIO, you would have some protection as well as the finishing step.
You can’t really do a one step polish with a medium cut product. It will always leave marks no matter how much you soften up the pad. If you start with a medium cut, you need to add a second step of finishing with a fine polishing/finishing cut.

Re: Marks after polishing
You will need to polish it. I would use Menzerna Super Finish 3500 or 3800. Use a polishing pad.
Have a great day and KEEP ON ROCKING!

Re: Marks after polishing
Thank you. I will try to correct this.
Do you have a tip about rpm and pressure? How many RPM should I set for 3500/3800 Menzerna with polish pad? It is better to put more rpm or low rpm and more pressure to the machine?

Re: Marks after polishing
Set your speed for medium don’t press down too much just let the weight of the machine glide across the surface, move slow… On a 2 x 2 section from right to left , make sure it takes about four seconds.

Re: Marks after polishing
Those are absolutley not marks from finishing with Menzerna 2500. Menzerna finishes down pretty nice.
You would not see markings like that even with Menzerna 400.
Something else is going on....
What vehicle are you working on?

When you say
RPM
This implies a rotary polisher.
If this car has soft paint, could be holograms you're inflicting into the paint.
Do you have an orbital polisher? If so, re-polish using an orbital and then inspect.

Re: Marks after polishing
What it looks like to me is clear-coat in the early-to-mid stages of failure. The streaks and polisher marks left behind are probably caused by polish residues embedded into the failing/porous surface.
Was this panel very dull and oxidized looking before you started?

If not, than a 4.92 inch throw DA machine might just be the culprit......

That's 125mm aka 5" backing plate.
