On the supporting board above the wrench is the normal sized one I modeled this giant wrench from. It has bits of grease and dirt worked into its surface. This is the used look we were seeking to duplicate when we added our glazes once the silver paint has cured.
The glazes only took minutes to put on and then mostly wipe off with a damp rag. Bits of dark color were left in the crevices of the tool just like in real life... except for those who are really fussy when they clean their tools. I tend to not worry too much about that type of thing.
The finished wrench really catches the light with it's silver metallic. The glazes make the wrench read well and make it look real. It was a very fun and easy piece to do. My time and the time on the MultiCam added up to about four hours in total.
