Clovis,
Thanks a million . I guess the biggest part of weathering for me was/is the trial and error. I truly do enjoy the weathering process. I've never been very good at thinning paint for my airbrush, so I've always used the washes/dry brushing/pastels system. I've also used oils, but feel more comfortable with the enamels. I believe there's always the fine line between doing enough weathering to have it be seen, and going too far, as to overpower the base colors. I love to look at all types of models, to see how others have achieved their results.
