Guys I have got all my parts for the car wet sanded with 600 (will be spraying a metallic). Final primer was regular 2 K. This took several days and what I have read on the forum is I need to scuff each part before painting since I am outside the 24 hr window. I have the grey pads ( 800 grit) will that be the right choice or due I need the purple pads ( 600 grit)?
