Final Sanding Primer
For your final sanding you can do it dry or wet, by machine or by hand. We\’ve chosen to wet sand while using a block. You don\’t necesarrily need to use the block at this point, but it can help smooth out any minor imperfections. You should do your final sanding with 500-800 grit paper. The guide coat is optional here too, it does help ensure that you have sucessfully removed your 320 scratches.
