Engine Paint

Here is a question for you Spridgiteers.Is there a source for engine
paint for these cars other than the Moss spray cans? What I am looking
for is a bulk type paint that I can squirt from my spray gun.The color
I am in need of , at this time , is the dark green one. So give it
some thought please. In the mean time I am off to the British Car
Swapmeet, in Portland, Ore., see you there Paul.
Thanks you guys,                                 Brad at British
