Yep, I've been looking into it in last couple of days and it's a no bueno option for cast iron and it's inherit properties (cracking with excessive heat et al).I would avoid powder coating. Any subsequent damage is not easy to repair and any moisture will eventually get under the thin plastic coat and lift it, as will oil. Good old paint is far better, and cheaper too.
It'll be case of paint stripper and/or electrolysis (for smaller pieces), followed by etch primer and the coat(s) of paint. Speaking of which and me being a believer that there's no such thing as a silly question, for cast iron, normal metal paint? is there something better?
Asking for a friend...
Plus Gas every time on small stuff. If you need to soak then I'm with Deema diesel or paraffin. I use evaporust for little bits, just find it easier to chuck them in a jar.
Yep, I have PlusGas on order for a weekend job. I also ordered a impact screwdriver and the widest flathead hex bit I could find, hopefully it'll do the job.
