1. A pretreatment composition for treating a metal substrate comprising:
(a) a group IIIB metal and/or a group IVB metal present in the pretreatment composition in an amount from 150 ppm to 1000 ppm metal, measured on total elemental metal; and (b) a rheology modifier composition comprising colloidal layered silicate having an average diameter of from 1 nm to 30 nm. |
