I have been sanding down my doors and carefully making my way through the layers in hopes of finding some markings. I always do this when I restore an old truck. I call it "Forensic Bodywork"
Anyway, I found 2 diamond shaped symbols approx (6" each) side by side.Very faint. The left hand diamond appears to be white and the right hand diamond is black. I can barely make out the word "FLAMMABLE" in red above the diamonds.
One of the layers is a very light green and another layer is bright yellow. There does seem to be an OD green layer as well in the mix in addition to the current OD green top coat.
I am hoping someone may have seen this or recognize the insignia.
Thanks!
