I know I have asked this before. I ordered some zink phosphate from eastwoods. It is almost black. Before I removed my hood hinges and shock towers they were more of brownish color, not really yellow but definately not black. I had the shock towers and hinges media blasted, Maybe my mistake. Now on a 68 I have heard the hinges were phosphate and oil. Is this not the same as zink phosphate? Now what color should I be looking for?
