I have a 1977 Cutlass Supreme which I'm redoing. I'll be painting it tomorrow. I'm going with Pepper Grey Metallic as the main color and Black Metallic as the rally stripe color. I was wondering what's the best way to lay the rally stripes down and the best order to paint them.
Should I spray the black base first and then mask off the stripes to save on masking time and paper? Should I spray the whole car with the pepper grey metallic and then mask off the stripes and shoot black? Or should I paint the whole car in grey metallic, clear it, wait for it to dry, and then put the stripes on at a later time so I can take my time laying down the stripes perfectly?
Also, what's the best way to mask off rally stripes?

Sorry for the long-winded post...
