I was tired of yellowing headlights!

Ok, the Lexus is 11 years old and I probably should have done this earlier. I don't believe everything I see on YouTube, but this process sounded authentic, so I tried it.

• Mother's Mag and Aluminum Cleaner around $11—yup, on the shelf at Canadian Tire.
• Mini foam thingies for my power drill around $21. You probably already have something like them.
• 303 UV Protector—I've been using on my Morgan top and tonneau covers. Bought at Ron's Auto Upholstery.

There are lots of crazy suggestions on other YouTube posts, but this is the one I followed:

1) Wash your headlights thoroughly to make sure there is absolutely nothing on them like bug bodies, road debris or tar.
2) Put a little Mother's all over one of the clean headlights.
3) With a foam pad on the drill or other fancy buffer you might have, start the polishing process. Within three minutes you are going to be pretty much finished.
4) After headlight is looking crystal clear, wipe any residue off.
5) Apply small amount of the UV 303. Follow the instructions. End with a little hand buffing with a cloth or paper towel.

Here's with one done. (Can you tell which one?!):

Here's the finished project:

Give me a Toonie, I'll do yours for you and save you buying stuff you possibly won't need again.

However, you really should have 303UV Protectorant.
