I know that some time ago there was a posting about the OD color. Since, the search is not working I thought I bring this up again. I need to get the proper OD color mix (hopefully for Lowe's) for a future project. Thanks.
Some time back I did post the formula for the correct Olive Green. The formula I posted came from taking a paint sample from one of the big Cannon Restorers--Steens and having it analyzed by Home Depot and Lowes. If you need authenticity drop them a line and see if they will send you a sample.
Until we get the search function working it may be a while until we find it. I will get it posted in the Cannon plans when I find it.
Until then the colors that George and Rick mention look just fine.
