Let me know how this looks to some of you. It's an experiment in producing a partially rusted out panel on a 1/64th car like in my junk yard. This is a hot wheels Duece roadster. The inner fender panel was taken out with a dremel & replaced with one made of a disposable aluminum baking tin. The panel was pierced with a needle in spots & then had ferric chloride ( circut board etchant) dripped on it. The overall rust effect was Floquil rust sprinkled with a mix of baking soda & powdered brown chalk.
