Well, I bought some Meguiar's Plastix cleaner about 6 months ago, because I noticed my head lights were becoming less clear and more hazy. I've used it sparingly no more than about 2-3x. They cleared up no problem, but within the past month or so, I've noticed my head lights have increasingly turned from being a nice, clear, new-looking housing to now a yellowish and really crappy looking housing...

I've only used this particular plastics cleaner to clean my lights... The last time I used it was about a week ago and I thought perhaps this was just the weather causing this, but I noticed that even after last week, my lights have now gotten worse! They look even more yellow now!

Sorry, I don't have pics to back my post.. I'm at work. I went out just now to get a pizza pocket from 7-Eleven and was like man, wtf my lights look worse!!! So anyway, just wanted to know if anyone else had this problem after cleaning their lights??

Thanks!

 

Most car headlight lenses have a UV film on them to protect the polycarbonate lens from yelllowing. It seems you have polished that away at this point. I would suggest you put some wax/sealant on it after you polish. That should make it last a bit longer. I don't know if there is a way to replace that UV thin film

 

Man that sux!! Here I am thinking I was gonna do something good for it..
Well, thanks for the info man. I was unaware of the potential damage it may cause.

Bump for suggestions, anyone?

 

I've used this product for a while now and never had a problem...G/L with your issue

 

Just posting a reply to edit: I did some research and it turns out the problem was caused by something else and not Plastix...

After speaking with a friend whom I had detail my car months back, I asked what he had used to clean my head lights when he performed the detail. He told me he uses chrome wheeeeeel cleaner ... WTF!!? The cleaner, highly abrasive, tore all my UV coat off apparently. Normally, I would not have anyone detail my car.

I learned a costly lesson.

Sidenote: I picked up some new lights from an 05, complete housing and all, from a friend/another forum member.

 

and to think i was gonna throw out my almost new bottle of plastix! thanks for the update.

 

Yeah man, sorry for the confusion. I was completely unaware that he used wheel cleaner until yesterday.

 

that's good news for the plastix users here. I'm guessing you'd have to use the plastix every week for a couple of years to remove all the UV layer. I wonder what people on here do when they wet sand and then polish?

 

I read in the DIY section that after they wet sand with high grit paper, they have good quality clear sprayed on them (not the spray can type).
