Not true that a color match can be made for a factory color in each brand of paint. Had my 69 Coronet painted in B3 with Sikkens paint. Its nowhere near right, but I actually like it much much better. I thought I was crazy and when my fenders got damaged I had B3 mixed in 3 other brands of paint and none matched each other or the paint on my car. Should see the trouble there is getting B5 'right'.
