LOL, this brings back a horrible memory.
I was a doing a demo when I was a paint rep that I had no business doing, a complete SS metallic on a Granada as I remember. Anyway, I could paint all day long with BC/CC, completes, blends it don't matter, I was confortable as all get out with the BC/CC but hadn't painted any SS metallic in years. I had no business doing it but thought I was a bad A and went for it. Can we say "Tiger stripes"? HOLY COW what a mess! I tried and tried to fix it before I had to give up, it was crap. Had to be sanded and painted over.
