That's the good thing about using primer....it can absorb scratches that would have been in the plastic. If they're not in the plastic (or, even if they are), just get some slightly finer grit and sand/polish the scratches out. It might take several grits of progressively finer paper to get back to a totally smooth surface, but as long as you aren't changing the shape of the panel(s) or eliminating detail points, it shouldn't be a problem (other than being more time consuming).

What grit did you use to sand the primer? Are the scratches fine or coarse? Are they all the way through to the plastic, or are they just in the primer?

What you do next also depends on what kind of paint you are going to use. If the scratches are fine and only in the primer, you can use an enamel that will probably fill in the scratches and hold the paint very well. The only drawback to this might be if you polish the paint and it reveals the scratch marks. A laquer or acrylic enamel (which are thinner than regular enamels) will probably show the scratches without polishing. But that depends on the depth of the scratches.

Keep in mind that polishing is just "paint removal". Using sandpaper obviously removes paint, but so does polishing (just not as much). So, if your scratches are small, and you have a polishing kit, you can use it to remove them from the primer.

Take your time and it will come out like you want it.

BE SURE TO SAND OR POLISH 90 DEGREES ACROSS THE GRAIN OF YOUR PRESENT SCRATCHES UNTIL YOU CAN'T SEE THE OLD ONES.

Have fun!

A few coats of primer with some vigilant sanding in between should do the trick

I would probably get some 800 and take the plastic down a little, then some 1000 back across it to smooth the panels out. You can get 800, 1000, and 1500 at Pep Boys in there body prep area. Those are made for WET sanding, so be sure to use water and take your time.

Then, I'd reshoot the primer and see how it looks in reflected light. From there you should be able to sand out any imperfections with the 1000 or 1500. I'd also use the duplicolor scratch and fill primer if you still have some minor lines showing and don't want to sand down the plastic anymore. It shouldn't take too much to get them out unless you really got deep into the plastic.

IMHO 600 is a bit too coarse for 1/24 cars unless used very lightly.

You didn't say how much area is scratched.
