Painting Rotors to Prevent Rust

I think the rotor looks just fine - however, the rest of the wheel is a mess -

We drive the car quite hard and the rotors get cherry red. That is about 1300 F. The paint said 900 F intermittent.

Do you recommend that over something like this? The car only sees occasional spirited driving, so I don't think the rotors get super hot.

You're not wrong. Seattle weather hasn't made it easy to keep her pretty and clean.

Fer sure, fer sure. One year, a few years back, my father and mother, who retired in California, bought me a "California Duster" for my cars.

I reckon he didn't realize that we didn't have "dust" here in the PNW. Ya can't have "dust" when it rains twice a day -

My only concern is that requirements to cure a higher-heat primer may be more stringent. That's just a guess though. Also, might there be advantages to staying consistent with the primer and paint brands?

Other than that, yeah, it seems like the Rust-Oleum one has a greater benefit.

Yes, I believe you have to cure it at high temperature.

Yeah that could be true. I would go to you nearest pepboys and read the cans. 500 degree may work if you are only cruising around

The VHT paint said to bake the parts in the oven for an hour at 200 F.
Which is totally doable, but a PITA!

Sorry for the late update. I ended up using Dupli-Color Engine Enamel Primer and and silver Caliper Enamel with Ceramic. The paint has held well for the last couple months. It's a big improvement over swaths of rust, but the silver doesn't look very good. I'm planning to redo it black.

YIKES! One of those lug nuts has a nick on it - how do you stand that?

You can get a high heat clear coat (https://www.amazon.com/Dupli-Color®-.../dp/B0082LGJ2C), but it's not necessary.
