3000 grit scratches

jet black paint

So I tried getting some deep scratches out of my car and brought them down to 3000 grit but I can't get them to polish/compound out. I know my trunk was repainted and thought it was just soft clear coat but other spots on the car do same thing.

I have tried 3m's rubbing compond, meguiar's standard compound and polish, and meguiar's m9 swirl remover with no luck using meguiar's DA machine.

Any suggestions?

I've used the cleaner wax by hand for light swirls, I def diminished what I had and also hid others nicely . Not sure if it is more potent than what you have tried already though. I have a 2013 jet black as well.

What kind of pad are you using?

The meguias DA is a real gimmick but if you insist on using it be sure you are using an aggressive pad. I'm not sure what pads they come up but knowing meguairs they are conservative and likely just give you finishing pads which have no cutting ability.

I am using the red cutting pads. it shines up the paint but if I look at a certain angle I can still see the area I sanded. looking really close I still see very small scratches. I am thinking the compound is just not strong enough.

The 3M compound is pretty aggressive. I'm surprised you're having issues. I'm not familiar with their red pads though. How do they compare to LC orange or yellow?

Chemical Guys V36 or V34. Use an orange pad and it should work the scratches out. I have good luck with it every time. I just used it to polish my camera lens on my phone last night also.
