Ok, I remember this now about the Flambeau paint fade complaint....I worked for Case 1973-75. The upgraded red was indeed used onwards in the 70's series ag's. and LGTs. When DB and Case merged their lines in paint color that was 75, and the upgraded red become more popularly known as power red, and desert sun was gone, to be replaced by power white.
Power red is always power red when it's Case. The McCormick red a significantly redder shade. A few years back I found the Lobster Red Rustoleum at Lowes, only to be dropped but still avail online. I see you mentioned it in a previous thread. Chevy Orange also a close match. Its all according to the eye one is pleasing. Personally, nothing matches Power red exactly except power red. But to the user unbeknown to the story, any of the close matches work.
Ironguard Power red with hardener is some of the best machinery enamel I have ever used. Very tough, nice gloss, easy to apply with a decent gun, and very affordable. Heck, the reducer and hardener costs more than the paint but goes a long ways! Do your self a favor and just get the good stuff that will last for years!
