On the Mercedes there was lots of chrome.I have found that there are 2 ways to make it look old and weathered.Remove all the chrome in an amonia bath overnite and then repaint silver or aluminun, and then weather ,or do the following.Take the brand new shiny part and with very fine sand paper ,600 grit or above ,sand in tiny scratches and generally dull the whole surface.Take some very thin raw umber,the consistancy of skim milk and lightly paint the surface and then force dry with a hair dryer.Between coats you can rub the surface lightly with your finger to create a sheen.Continue with the raw umber coats until the disired effect is achieved.Dont worry if it looks bad as that is the effect you want.Take some black,grey and burnt sienna pastels and do your magic working in dirt and dust and the occasional rusty spot.
I have found that working with thin acrilyics and pastels in combination is really the way to go when weathering.Although it does require some proctice to get it right the results are great while you are having loads on fun with the process.
I hope to have some new pics up next week,including pics of the weathered towcar.
