Copper Prep #4

Sure wish there was a way to put more than one photo is a post, then I could write the whole thing together instead of piece meal - last step on top of first ones! Anyway...

Here, I'm using a brush to put on flake white - actually I used some Cremitz white here - that's been thinned with mineral spirits or turps. I started with the brush to get the stuff on there, then I smoothed it out with my thumb.
