Virgil Suarez, aka Dr Cranky, is one of the most imaginative auto modellers around and he has fine tuned a number of techniques to weather models (he loves rust, gunk, and worn paint...and scrapple on occasions). He is also a professional writer and he has just published a book on modeling . The link to the book is below
