I've just started doing a space shuttle model kit by revell and having awful problems with the paint not going on well. I decided to do something about it as the previous kit i did by airfix was just as bad. The instructions suggested washing the plastic in a mild detergent before construction. So i soaked the lot in a washing up bowl with warm water and fairy washing up liquid and then let the lot drip dry. It doesn't seem to have to have done much good, the paint still washes around on the plastic and doesn't seem to go on very well. Has anyone got any tips on how to paint these plastic models?
