LCA Correct OEM Color - 67 Cuda

Years ago I ran across an article about LCA restoration. IIRC the article said media blast them then paint them with this other Eastwood product that was the same color of the freshly blasted LCA (cast iron gray?), then use the Eastwood cad color over it. The article mentioned you should mask a few inches down from the lower ball joint all the way around so when applying the cad color paint (or maybe it was called something else) it would mimic dipping the LCA in cosmoline. Hope this helps as it’s to the best of my hazy recollection!
