paint gelcoat

Looking for since help. What are these marks in my gel coat? I was removing oxidation with Meguiars, but I can't get rid of these marks to make it look even. Thank you.

I am trying to see if anyone has the paint code match for a gray hulled 420 (I think all gray hulled SR's the same). I know its gelcoat but want to touch up a few scratches without trying to go through a gelcoat repair. Thanks in advance!
