The white wash was done with heavily diluted enamel white paint (Humbrol). Just brush on thin layers much as the crew would have. Then, before the paint dries, use a flat brush to streak down the paint to create the 'worn of ' effect. you can alter the amount of streaking and create that run down effect by loading the brush with thinner, but clean the brush inbetween as otherwise the paint doesn't diluteI was realy after the effect of whitewash being washed of through the rain, rather than being rubbed off. I think it worked o.k.
Maybe I should write a little 'how to' feature..
Hi Slodder, thanks for the original tip to add some bit's around the log to imply that the Germans had hightailed it sharpish. It has really completed this dio.
There are two crew members in the Sherman however I think they don't show well in the other pic's

Cheers
Henk
