Primer Sealer question

Ok, I'm using Finish 1 2k Urethane primer. I've already sprayed it on the hood I'm repairing. I have sanded the hood smooth, but I've got small but noticeable sand scratches that I'm afraid will show when I apply the basecoat. Will a Primer Sealer solve my problem since it may fill in the scratches???

What would you do??? I'm ready to paint, but I want the hood to look as good as possible. Any advice or help would be appreciated.

Mr Bolt, what grit paper did you use?

You might try sanding the scratches out with a lighter
grade of sandpaper, and wetsanding.

What grit sandpaper did you finish with? Sealer will cover 320 grit scratches. If you are concerened, you can go finer to be sure.

I usually wet sand with 400 grit, but this was going to be my final coat of primer so I wet sanded it smooth with 600. I guess some dirt somehow found it's way under my block. It was real smooth, and flat... until I noticed what looks like a few deep 120 grit scratches.

It's always better to sand the scratches smooth instead
of priming to fill them. Less chance of them shrinking back later on.
But to fill them, a coat of reduced epoxy as a sealer will take
care of most sand scratces.
