Re: "Though no idea how it'd handle for stuff like cam shafts."

Well the metal quality might be OK but the surface finish is the issue.

That said there are a number of "liquid polishing" techniques. One of which is called "liquid honing." It use a proprietary mix of plastic beads with embedded abrasive in to give a surface finish below 64 microinches (1.6 micrometres) and even to 0.4micrometres.

It's the metal quality that I'm more interested in. The polish on the lobes isn't a big issue, but whether or not the lobes or other parts will fail under load. Then again, I guess the pressures on a cam shaft aren't really that great. As I write this I'm wondering if I could make my own clay mold and get someone to fill it with an appropriate material for me. Getting the exact "as new" specs (especially the lobe shape) would be nice, but I doubt the maker is willing to let such details out.
