Ok..My USMC M60 w/ reactive armor is complete..my desert diorama base is complete. Now I need to give the tank a wash to give it the used look. Can anyone give an amateur a step by step on how to wash it??? It has one coat of Model Masters Enamel US Forces Desert Sand on it right now... thanks guys!

After you've glossed the model and added your decals,use a dark brown, burnt umber or van dyke brown. Mix this with a lot of thinner, at least 90% thinner. Take a fine brush and place a little bit at all raised detatil and in panel lines. Capil;arty actio will draw the paint along the edges giving a shadow effect. DO NOT slather this over the whole model. Make a similar mixture with black for the grills and slop it in there. You'll now have a nicely shaded model. Drybrush over the high spots and raised detail with the base color and a lightened base color. Find some chalk pastels to match the terrain you depicting and scrub this on the wheels and lower hull fading as you go up the tank.
