When dealing with procedures of the past, it helps to understand the technology used during a specified era and the changes that result over time. We discuss the condition and appearance of these NOS and original items today but they do not have the same fundamental features that they possessed some 40 years ago. Rather than debate the characteristics of these components, it is important to understand how these parts started out and the changes that may have taken place over time.

The grill and the shaker bubble were painted with the same engineered paint color. The plants would have ordered the paint in bulk but variations would have occurred due to slight changes between the batches. Next you must consider the bonding surfaces and material differences that existed between the two manufactured parts. The grill had the textured paint sprayed directly over the plastic composite, molded surface. The plastic would have exhibited aging color changes, that over time, would have altered the hue of silver paint. The same logic for the shaker scoop. It was a fiberglass composite material BUT used red oxide primer , on most of the bubbles, as a basecoat BEFORE the metallic silver was applied. The darker red base coat could have altered the color cast of the argent silver paint. If some of the shaker bubbles had a greater amount of silver paint material applied, a difference would have resulted in the depth or density of the silver coating. You have two totally different surface materials, aging in a manner that could impact the appearance of the colors as time progressed. Don’t forget that the flake is a true metal material that also oxidized, at rate specific to it’s environmental surroundings. An original grill will be exposed to conditions different than those of the shaker bubble. The engine heat alone will bake and alter the silver paint finish of a bubble.

If you understand the specifics that affect the overall appearance of paint, it is easy to explain how these subtle color changes will occur.



Mike, cant disagree with you on that and dont.

regardless of all that, YOU need to be able to tell the difference between the two shades and the origin of what was what before it was sprayed, before all the effects you mention have taken place.

and until YOU have held in hand, looked in several different cans of REAL NOS Factory packed original formula unsprayed paint/ toner, etc, or mixed original formula dk/med using all original toners, etc, then spayed many different parts over 20 plus years, using the many different variables (that you mention), of the originals as a guide, YOU dont have all the knowledge YOU think YOU do.

so why not just post pics of your grille and bezels side by side to you shaker for everyone to see, not just me.
