Abstract: GM(1, 1 ) prediction model has been constructed according to Grey Theory. The change of gloss retention and colour aberration of the black automobile coating under the condition of dry-hot natural environment is predicted. The applicability of the constructed model in black automobile coating aging behavior was investigated. Prediction results of gloss retention and colour aberration for black automobile coating show that the prediction accuracy grade of the constructed model is 2 or above, the maximum relative error between simulation value and the actual value is 5. 4%o, and the constructed model can be used to predict the natural aging behavior of black automobile coating. It is predicted that the service life of automobile rear bumper coating is 24 months in a dry-hot natural environment in Turpan, Xinjiang, China.
