Polish your yellowed headlights.

[PhilA]

I've used a few types of plastic polishes. Note the 3M stuff is quite abrasive and seems to have all sorts of "interesting" compounds in that soak into old crazed plastic and cause it to haze.

It has another good use, it takes bugs off the leading edge of your hood very well! I dislike putting clearcoat on headlamp lenses because it peels once it's taken a few stonechips.

I use Meguiar's Mirror Glaze on my trucks, it's what I used to have to use at work at the airport for cleaning the lexan windows on our fleet. (Read the bottle, it says it's Beechcraft approved), I think it's water based.
It's not very "powerful" compared to the 3M stuff, but it is very good for week-by-week cleaning of the vehicle. Does well on the dashboard etc where the clocks and radio fascia tend to get scuffed by me wiping the dust off with my fingers or sleeve when I can't see them in the sunshine.

I use the 17 and 10 bottles (cleaner and polish). Got them at O'Reilly.

Just don't keep it in the car on a hot day. I learned this, it seperates and goes nasty

About time for me to try the paste, they keep getting yellow faster.

Great tips guys,
Dave

...look for polishing "paste" that has a blue tint as BLUE and YELLOW tend to optically cancel one another, thus reducing the "yellowing" of the plastic lense.

You really need to seal the plastic once you polish it...really. Give the Glassylite product a try.

I just happen to have a big tube of Colgate that has blue in it. I'll try it OTM!

Thanks,
Dave

It shouldn't matter if no residue is left behind after cleanup. I used red gel and there ain't no red tint to it.

I just pulled the trigger on the Glassylite and it should be here in about 5-7 days. Got it from Amazon fer just under $27 shipped (free shipping).

I take piccies of what my headlights look like now and what Glassylite does to them. The clear coat I put on the headlights over a year ago did an okay job at keeping the lens clear...but the coating itself is spotted. You'll see when I git all the piccies done.

I'll keep en eye out for em.

Just tried this toothpaste trick last night. I'm pleased to say it works; it's not new lens clear, but still a very cheap and convenient improvement worth the elbow grease.

[Dave's Civic Duty]

Still didn't get to mine yet. I've been driving around with my toothpaste for a few weeks now on my passenger front seat. This will keep me honest, I'll try to get to it tonight!
