I can say that the changes were rolled out on a plant by plant basis, as they were ready. Too much waste to change over 7 plants all at the same instant.

The changes were rolled out even within the same plant. In 1987 Line1 (pickups) at Flint Assembly was still high solid enamel but Line 2 (Blazer and Suburban) had already converted to base coat/clear coat. A similar transition occured earlier when Line 1 was still spray primer but Line 2 had installed the ELPO tanks.

Keith: Very interesting; so I presume that at one time the same model truck made at different plants had different type paint; correct? When you get a chance please find the aprox. date of changeover to enamel. Just off hand you would think it happened in the 80's rather than the late 70's? Larry
