Rub the paint with your finger. Try to make it shine. You might have the begining of paint chalk. Too much chemicial not enough scrubbing. Are the trucks non factory paint??? If they are chances are the paint is of poor quality.

If the fleet is on the high end side, suggest to the owner operator, to have the trucks sent out for a wax/pollish. Do they run in the winter salt/calcium areas??? These chemicials can kill paint too.
