I think you need to have at least one laquered turd and one chrome plated turd. As far as contents, I would like to suggest corn and peanuts, maybe some veggies for fiber and some artificially colored products for color.
How about electro-plating a turd - it ought to be possible - start with a nice firm one, embed a wire in it, then alternate it between the freezer and the plating bath until there’s a good layer of metal on it. You might need to poke it a bit to get it submerged, but if you have a low-flush toilet, you’re probably already highly skilled at that.
Thinking back to the movie Christine, based on the Stephen King novel of the same name, Will Darnell looks at Arnie’s 1957 Plymouth Fury and opines, “You can’t polish a turd.”
Well, first you’re going to need to assemble a few supplies:
one of those little nets people use to scoop fish out of aquariums
shoe shine kit
shoe polish (brown)
Since you’re new at this, you’re going to need a lot of practice to perfect your craft. The personal manufacturing capabilities of a single person are likely insufficient for you to hone your skills in any reasonable time frame, so your highest priority should be on increasing your supply of practice material. Hanging around a few restrooms and politely asking people not to flush when they’re done ought to do the trick. (Don’t forget to bring your net!)
Once you’re ready to get started, use the same guidelines you would for a nice leather shoe. I’d recommend a wax polish for a glossy shine. Consider applying a protective non-silicone finish when you’re done to repel water and stains.
