A couple of other color matching options:
1. APS Tower Paints (APSTowerPaint.com) will make paints if you give them the original Rootes color code. They sell a spray rattle can and a 2 oz liquid jar of enamel touch up paint. You can purchase paint from them and then color match. I have purchased both a spray can and the enamel touch up paint from APS Tower Paints.
2. Jan Servaites <jservaites@woh.rr.com> sells color samples. I purchased a color sample from Jan. The color sample I received appears to be a sprayed CD. You can color match Jan’s sample.
