Help

I need some expert advice on which black color (Semi-gloss,satin,flat etc) to use?

1) Front and rear fiberglass "spoilers" sections below bumpers

2) Gas tank

3) Front hood springs

4) Air Box (Paint overspray)

5) Rocker panels

6) Charcoal canister (has paint overspray)

7) Plastic rain tray (overspray)

8) Licence plate bracket

9) Parking brake

10) Pedals

Thanks!!!

Satin black on most everything, powder coat is good on the pedal set, and try to clean the plastic parts carefully?
