Got the touch up paint yesterday for the 66 code Regal Red. It seems to be a perfect match. A 3 oz touch up bottle was $12 Plus $9.95 for shipping. Each addition item would have been a addition $1 for shipping. Certainly a lot more than I needed, only needed a couple of dabs for the underside of the hood. I bought some from NAPA 7 yrs ago, the smallest amount I could get was 1/2 pint and that was $40.
They will mix anything from the past, plus anything else, if you have the codes. Thinking about ordering a few spray cans@ $19 to paint some rims. Should have ordered a bottle of touch up for the 07 Impala and the 09 Silverado, just in case.
