You know guys/gals... I feel like s_ _ T! I repainted my rear quarter extensions on my 67 Stang Fastback and all I did was sand them with 400 grit and then sprayed Electron Metallic Blue color and clear. The extensions came out darker than the body. I left the first spray of color in the extension and sprayed new on top without sealer since I thought that the original spray was the same color. Did I make a mistake? Should I have sanded all the original color off first? What can I do?
