Can I prime and seal can lights with a heat resistant coat before using a universal spray paint for color?

I’m in the process of painting our can lights, but I can’t seem to find the right color in heat resistant paint. Do you think it would be okay to prime and seal them with a heat resistant coat first, and then use a universal spray paint for the color?
LED bulbs don’t produce much heat, so you don’t have to worry about using heat resistant paint. If you’re not already using LED bulbs, you might want to consider switching to them.
Hey TJ! I’m using an LED and I’ve been researching the best paint to use. I keep seeing recommendations for paint that can handle 300+ degrees, but most spray paint only withstands 200 degrees. Do you think it’s just better to be safe than sorry with the higher temperature paint?
In my experience, most people just paint over can lights with the same paint they’re using for the ceiling. I’ve never really heard of using heat resistant paint on a light fixture since it shouldn’t get too hot. If you’re using LED bulbs, there’s really no need to worry about it.
Thank you a million!

I painted my can trims with regular paint 20 years back and they are still in good condition. I also have 75w incandescent light bulbs.
Expressed gratitude.
Mentioned that LED bulbs emit much less heat compared to incandescent bulbs.
My family and I recently painted our radiators during the summer, and from what I’ve found in my research, modern spray paints are pretty durable and can withstand a significant amount of heat, which is perfect for radiators. I think any good quality spray paint should work well for this project.
Honestly, it’s a bit of an overkill with all the lights and radiators, you can check out this link for more info on high temperature coatings: https://resources.forrestpaint.com/when-to-use-high-temperature-coatings#:~:text=For%20temperatures%20above%20400%C2%B0,prevents%20corrosion%20and%20preserves%20aesthetics.
I decided to change the color of my 4000W forced air heater covers to black using regular rustoleum paint, and surprisingly, the gloss remained unaffected.
What temperature are you expecting them to reach?
