Cut the green with 1500 2000 3000 Look for scratches as you go. Hard work. 4 coats isn't that much. SS is soft. Careful around the edges. Best thing to do is a small part and practice. Start finer and work back as you have to versus starting too coarse. 3000 is DA with double foam interface. Lots of water. what u using for product? I like the 3M perfect it.
600 where u spray the blackout. Tape it off and sand just up to the edge. Then grey scothbrite up to the tape. real light.
I don't like plastic next to where I spray. Always paper along the edge,Plastic everywhere else. About to do it too,I'll post up some pix as I go.
