Need help removing sanding scratches.

This is my first car project and therefore first time painting. I'm pretty happy with how the paint turned out, EXCEPT, I can't get all the scratches from wet sanding removed. Everything looks nice until you catch the light at the right angle, then you can see the scratches. I wet sanded using 1200, 1500, 2000, and 3000. I buffed with the Norton Liquid Ice system, wool pad, blue pad, white pad. The buffing part makes me nervous...My question, Is there a product to 'fill' the scratches instead going back and wetsanding and buffing more? I don't have a picture of the scratches, but here is a picture of the paint itself showing pretty good clarity and reflection. Any help you can provide will be appreciated, Thanks!

Are you seeing sanding scratches or swirl marks? 3000 paper is very fine a shouldn't leave scratches.
You need to follow up with a polishing compound with a foam pad. Then maybe a glaze type product.
Buffing takes time and practice and it is really easy to burn the paint. Never buff on top of an edge because
that is where the paint is the thinnest.
