I am trying to match the rear finisher paint formula given in Wick Humble's book at page 174. I have located Ditzler DDL 2862 and DX 265. I cannot find the DX264. Ditzler Tech Services doubts they ever made anything under that number. Is this a misprint? Does anyone know the correct number? Is it a texturizer? Also, the formula referring to 200 and 300 units mystifies everyone including Ditzler Tech. How much is a unit? If a pint is the base, is 200 units 2/10ths of a pint? Any help would be appreciated.
