This works with plastic and glass lights. Why metalcast over film? It's just personal choice.
There's two ways to do it. You could spray the inside or outside.
Disclaimer: If any damage exists it is entirely your fault.

Here's what was used:

Outside:
Thanks to xoSubieLegacyxo for information on his method used.

Remove foglights.

Sand the lens. (Chad used 400, 800, and 1500)

Spray desired number of coats. (Chad used 3)

Install.

Inside:
First remove you foglights. This varies from models and generations.

Remove the bulb, socket, and clips holding the lens on.

Heat up the oven to about 300 degrees F.

Put the lights on aluminum foil covered tray.

Toss them in the oven and wait about 10 minutes. I watched them until my housing started to melt.

Put heat resistant gloves on and remove the light from the oven.

Set the tray on a cooling rack or whatever won't be affected by the heat.

With your hands start pulling the lens off. Technique is up to you to find what works best.

After the lens is off hold it in your glove until it's cool.

Tape off the outside to resist overspray and spray the inside. Use as many coats as desired, I used 6. (pic taken after 3 coats)

Put the lens back in the housing and reheat it to help melt the glue.

Remove from oven and push the housing on a little more to ensure it is fully installed.

Allow to cool and install.

If it's darker than you want just pick at it with your fingernail and peel the paint off, no need to sand it off.

I know theres a smudge on the lense, that's bug guts that are getting sanded off after its all done.

Need picture of the outside to see how it turned out. I'm thinking it would look more OEM on the inside and last longer but that depends on how much more it's effected by the heat of the bulb on the inside.

So the spray paint is yellow tinted?

Why not get rock blockers or lamix film?

Pic of it painted on the outside is the only pic under the "outside" section

It's easier to apply and, if done on the inside, is more durable than the film. Plus the film has a chance of melting. I put my light back in the 300 degree oven til the housing started melting and the paint looks the same so it'll withstand the heat of the bulb

I have had film for well over a year, maybe two, and i have had no problems plus you get rock protection. But nice write up though!

Oh I see. I was thinking that was someone else's picture of painting the outside. Looks great.

The picture you posted in the outside section is of the inside of the lens. That's why I said you should post one of the ouside to see how it turned out in comparison to your friend's picture of the outside because he painted the outside of his lens.

Yep, my rockblocker is clear but I've been running it for 4 years and no problems with melting or adhesion. Plus it's kept my headlights nice and fog-free.

This is good to know! I was planning one yellowing the high beams on my integra this summer!

^ its more for how it would look with the lights off than anything else, but I am considering putting city lights in the high beams as well...

Although there are other options, like the films that everyone has discussed, this is a great, cheap, alternative for people who don't have a lot of money. Lamin-x can be pricey and if you don't put it on right, then you risk having creases. Remember, the RS fog lights have a convex shape. Great write up though! Might try this on my Hella 500 lights since those come apart a lot easier than the RS ones.
