Some informationh for those of you who are into refurbishing accessories and rolling stock. I searched for months for Lionel 3656 Green Spray Enamel, and purchased several cans of "almost correct" color along the way. Several sources promised exact match, but no one delivered. I finally found the answer. TASCO Auto Color, in South Austin will custom mix any color you want as long as you have about a 2 inch by 2 inch sample of what you want.
I took an old 3656 corral down and had them use their spectrascope on the inside of the part to get the original color. It's perfect. Not cheap, but perfect. I wish I had found these people before painting my Engines. Lionel black is impossible to replicate.
Regards,
Don
