The Aussie army where I served used to use a gloss olive green for it's Ford utility vehicles. Sort of similar colour to the old Landrovers that were about back then. Was probably mixed up like any other car paint by getting the paint shop to add colour to the can.
See your local car paint shop and they could mix you up a can of enamel with whatever colour you would like. Just take a sample and they can generally match anything, even if the sample is matt and you want gloss.
Hope this helps, Peter
You know why the rice bubbles that are at the top of the bowl dry out faster than the ones on the bottom when you get too lazy to do the dishes? You know the ones that you have to chip off with a cold chisel after a couple of days?
It's because they are closer to the sun!
See there's a little bit of science in every post!
