Scratch/Grit question

Guys, I'm painting my son's daily driver. First attempt at metallic. My question has to do with scuffing 2k primer before paint. Car has been blocked, washed, and masked. In the past, if I were painting (NON Metallic) over regular build 2k primer, I would use a red Scotch-Brite pad to scratch the surface. Will the red pad be too rough for metallic, or do I have to use the fine gray pad ? I don't have a gray pad, and wanted to paint the car in the morning.
 
If you scuff it with light hand pressure it will be ok. Especially if you are sealing it (you should be). Important to not use a lot of hand pressure. Just lightly go over the surface with it using very light pressure. Heavier pressure will cause it to scratch deeper and may not cover with your sealer.

Chris, thank you for replying. I was hoping that would work.
 
As Chris said, sealing is the key to not having scratches show in the base. The only time I use the gray is on a blend panel or a panel I am keeping the color within that is not getting sealed.
