According to the Service Parts Identification label on my 1987 Buick LeSabre Estate Wagon, the car is painted with a Dispersion Lacquer WA-L8592/U8592 (same color upper and lower). Does anybody know what kind of paint that is? The reason why I am asking is that a body/paint shop I visited today claimed that the paint had to be completely removed before a new paint could be applied. They said 200 man hours would be required. Anybody with a calculator can do the math... So is this true, must the paint be completely removed or can the car be successfully "over-painted" to give a reasonable appearance?
