doing a 1970 boss 302 mustang code t caddy apple red bought spi dk red to use color chip was really close problem is 2 coats match chip and would be a good match for overall but if you spray 3 coats for full covage its to lite . so if you go with 2 coats to get the color we want I see a problem with doing a repair or possiable over lap promblem. should have gone with factory code but ppg was $2200 gal basf was$1875 gal automotive art was $900 spi was $350gal my question would you go with the coats SPI or I was thinking use spi for ground coat followed with automotive art color
