Here is all the info I have gathered over the years for Merc Racing Blue:
Merc Blue paint info:
P.G. 17993, dupont b8110 - merc racing blue paint code, Dupont B8110A
(P.G. 17993 is so old that they don`t have a formula on record)
The dupont b8110a (old stock#) = DPC# 15663 (Color Perm Code AJ935) This color is found on Chevrolet 1981 (paint code 20) and Pontiac 1981 (paint code 7204) the name of the color is BRT BLUE. They could not get me the formula for the dupont but the same color is used on a Hyundai (color code HD) and they gave me the formula for this (Spies Hecker quality Serie 293)
Told them the dupont code B8110A & they mixed it right up in Imron. This is what its says on the can: General Motors code 20 1981 Bright Blue-Effect
this is to mix 48 oz imron (2 qts)
