hey AceofSpades;
try this, on a very sunny day put the finished kit out directly in the sun and most model paints will fade, but don't put it out when it's really hot this my cause warping, also I used to weather by dry brushing, areas by the panel lines this will create a nice effect like most people use with pastel chalks but you don't have to put a heavy amount then cover the effects with a clear coat right away, what I use for weathering is Acrylics, but paint the kits in Enamals, I've had no complaints, and it's just as fun as pastels too, but you decide on which is better for you, and the most cost effective for your pocket book
