I added some color charts of the powder coat colors available, mostly to highlight the black semi-gloss percentages. Way back, it was determined that 20 percent to 40 percent semi-gloss black (see first picture) were the closest to what was desired (Note, no 30 percent is available). The determination was not in respect to powder coat finishes. Also of note on the 3rd picture, is "Beige Hammer Semi-Gloss", which is a very close match to the wrinkle finish and shade used on the white (interior color code 62 for me) Rally Pac.
