Hi Craig, Before you start to paint with the Galmet Jade green, which is really light by comparison, you could consider a solid colour (rather than hammertone) in a Mid-Brunswick or Deep-Brunswick Green which would look really nice especially with fire -engine red cylinder reel and engine shaft....easier to maintain and touch up as well.
You may care to look at the Septone range of hammer-tone finishes as well....Here is the green...Click

UPDATE: this colour from Septone is now unavailable
