I did a pearl white Subaru STI a few years ago, and I base coated it with duplicolor white, then sprayed the pearl. The "pearl" was a white nail polish with iridescent particles that when thinned had no pigment, so it was just the pearl. Came out pretty sharp! Nice in scale effect. Anyways, not trying for tell you what to do, just sharing my experiences. Looks good! I'll be watching!!
