Yellowbird's Quote: "Many of the early engines show a color change to a more green shade over time. However, metallic paint does NOT lose its metallic properties."

What proof do you have that metalic paint does not lose it's metalic properties? Do you have old metalic painted engine parts that have been subjected to heat that have retained their metalic?

Yellowbird's quote; "Oh...and at least three different factory paint colors were exhibited. A very pale blue metallic, a turquoise-blue metallic, and a turquoise blue non-metallic. Along with some having black ribs from the factory, others not..."

So, you agree that there were metalics used but not on your engine?
