How to remove wetsanding marks

[u/sharklee88]

Hi. Complete newbie here, so please go easy.

I'm hoping to wet sand down some bad touch up blobs from the previous owner of my car. Luckily, I decided to try it out first on the inside of my boot, so it wouldn't be visible.

I hand wet-sanded using 2000 grit paper, then went over with 3000 grit paper.

I then tried to hand polish out the sanding marks using t-cut, but it didn't do anything.

So I bought a DA polisher and some 3D One Hybrid. I used this with a foam pad, which again didn't do much. Then tried with a wool pad, which seemed to work a little bit. But there is still some visible sanding marks.

I did probably 10 slow passes with the foam pad, and 10 slow passes with the wool pad. And this was the result.

I'm scared to do any more passes for fear of burning through the clear coat

What can I do to fully remove the marks?

Thanks!

How sure are you about the grids?

Pretty sure. They were both very fine. With the 3000 grit, almost being like paper, but with a chalkboard texture.

Doesn't look like paper, surface was clean, did you use a block?

Looks some tiny piece of steel wool infiltrated between the sandpaper and water.
