Right after my last post, I went digging for a gallon Ziplock bag to throw the Scout in with some Purple Power. The only one I could find had a little hole in it, so I had to limit my time with the paint stripping.
The Scout languished in the purple pond for a good hour or so while I played Minecraft. Went back to it, and scrubbed most of the paint off. It took most (if not all) of the brown paint off, and some of the black primer.
With bare plastic, black paint, brown paint, and blue paint showing, it got a really cool look, like it had been burned out or something. I took the opportunity to add rust powder... chalk pastel. Touched up the trim with a silver paint marker, as well.
I'm leaving the red and white part of the For Sale sign on the back wall. It just really looks like a big salvaged piece of metal the guy used to make this custom cab wall over a weekend or something.
