I have been told that if you have the NSN number for the color you need, Sherwin Williams Industrial Coatings can do it.
These #'s are for 1 gallon cans:
Desert Sand 8010-00-111-8004
Sand 8010-00-111-7988
Earth Yellow 8010-00-111-7968
Earth Red 8010-00-111-8003
Field Drab 8010-00-111-7943
Earth Brown 8010-00-111-7998
Olive Drab 8010-00-111-7940
Light Green 8010-00-111-7930
Dark Green 8010-00-111-7938
Forest Green 8010-00-111-7937
Black 8010-00-111-8005
You can go to your Sherwin Williams Dealer and ask them to order from their Industrial Coatings group the paint you need using the NSN number. I have not tried this yet, but I intend to. If someone else tries this first, please let us all know if it works.
I too have a need for "Earth Yellow" and have tried Aervoe. I used the rattle can, it comes out powdery, very wierd stuff.
Only my personal opinion - I DON'T LIKE THE STUFF. I've spoken with Aervoe at length and they don't believe there is a problem. OK, Whatever.
