I found a couple of PPG colors that are a very close match for the FED STD 595b colors on the FA-18E/F. The light gray for the top that is a good match for FS 36375 is "Cloud Gray", PPG# 35521, and for the top, PPG #35522 "Mack Gray" is very close to FS 36320.
They are so close I fugured that nobody would ever see the difference, if any.

I shot the bottom yesterday, using PPG DCC with DRX 685 flattening agent and DX 61 hardener.The whole bottom of the aircraft, including the centerline tank and pylon only used 9 fluid ounces of material, including overspray. Covering the gray in-mold paint job is simple, and doesn't use much paint.
The clearcoat will be PPG 2060 Flexed "N" Flat.
