I bake at 165, but in a convection oven, not radiant. Radiant will have a varying target surface temperature that depends on the color of the paint - very easy to burn.
How long? 20 minutes or so, then just leave it in the oven until it cools.
Thin layers only.. bake between coats.

If you have smaller parts engine paint works great.
I use this for fixtures and small items.
It is design to be baked on as it gives you tems and times right on the can.
And SUPER durable.

It does work, did it for years on test equipment and baking, or even setting it under hot lights, hardened it up nicely
of course using 'real' paint is better, but who has 100 bucks to paint small parts

atomarc is saying basically what a rustoleum rep told me. we were not baking but if applied to thick the base would be "green" as in not cure properly. we thought we had issues but in california that stuff may cause cancer, go figure

Adding the hardener to many enamels greatly enhances them...often the hardener can be found at the farm store. My Brother in law uses it in any acrylic enamel.....he prefers the "Rust Stop" stuff sold by Do it Best hardware, who for some reason does not sell the hardener. The hardener I think is the same as the old Dupont Duluxe hardener.
If you mix up too much paint it will get like jello...you can retard the hardening by putting it in the fridge...and use thinner to sort of ungel it....we used some like that on his clothesline posts and it is still nice after 2 years outside, and they had some surface rust when we painted them.

I make a lot of electronic control panels that are aluminum. First step is to etch the bare aluminum with a weak sodium hydroxide (lye) solution for a couple of minutes. Rinse, dry and spray paint with Rustoleum enamel . Bake the panels at 220 degrees F for 30 minutes or so. Screen print and they're done. I tested the paint adhesion by repeatedly flexing a panel until the aluminum cracked. The paint never chipped or flaked and was adhered right up the the fracture line.
