I sanded with 320 then last night but the scratches were still deep. I could see them but not feel them. once I rolled on a coat of paint they really showed through up close..

I have some primer thats spray on. I used it over my bondo work and those area's look good. But they weren't sanded down.

Is this how I should go about fixing the scratching? I was thinking of going over the scratchy area's hood, rear fenders and trunk lid then going and sanding it flat again and painting. But will the primer do the same thing and settle into the cracks? Am I completely screwed?
