If you're shooting with a light metallic (for instance, Sebring Silver Metallic) and a dark opposite color (like black), you will want to do one of thwo things. Either shoot the silver last, or shoot the silver first and cover it with a couple of light coats of clear ....... as the masking tape will tend to pull the metallic out of the paint when removed and ruin the light metallic color coat ............ learned this the hard way ......... over and over
Looking forward to seeing your "City Chevrolet" Lumina ........ built mine nearly 20 years ago ....... and it shows it
