More detailed post incoming when I’m less tired, but long story short, it works!
By “it” I mean that toaster oven, for the purposes of curing enamel:
This used to be anodized pink, now it’s gloss white.
Not a perfect job, but not too bad for my first try! I’m kind of excited to try other stuff with it. I picked the finish because it’s supposed to be durable against oils once cured - I’ll let you know how that pans out in the long term, but it at least looks a little more solid than spraypaint.
