Question: how many headlights can one bottle clean?
Document: Well, I was skeptical just like most of you. But, someone told me that my car would look so much better if I were to clean my headlights. Prior to then, I'd never thought about it. So, I went to Walmart and started looking around. I saw a few different varieties. I googled the reviews on my i-phone and saw that this product had so many reviews. Some favorable and some not. But, the majority were favorable.
I bought this after reading all about the other products & reviews many that seemed to take a lot of work needing a buffer and intense work. I received this product last week for my 2000 Maxima SE that "had" quite cloudy and a mild yellow Film over the headlights and side parking light lens. I took a damp sponge outside with me with the intent to just try it out. It took all of a minute to do one headlight!
I bought this product after looking up many different plastic cleaners/polishers and this was by far the one that gave me the best results. PlastX is just an amazing product to have regardless of what your headlights look like. My headlights looked hazed and just applying this product with a bit of elbow grease made it look like new!! In order to make the results last i strongly suggest that you use a polisher like a porter cable and give yourself a good 30 minutes or so per headlight.
I bought this Cleaner because of the good reviews it has. I wanted to clean the headlights on my 6 years old car as they became foggy and blured. I've followed the instructions on the back of the bottle, I even bought the "Megular's Even Coat Aplicator Pad" as stated in these instructions - no result at all.
It's easy to apply, and the 10 oz bottle is more than enough to do a lifetime of headlight restorations. I think I only used an ounce for both headlights.I knocked down the product down a star because it didn't do so well on a CD of mine. Despite using clean microfiber cloth, it looks like it may have added a few swirly type scratches to the CD.
I purchased this to &#34;clean&#34; the haze off of my very old and very yellow car headlights. I applied the product two or three times going by the instructions on the bottle. Either this is not the product for what I was trying to do, I didn't do something right, or this product didn't work. I couldn't tell any difference than before the product was applied. It looked clear for two seconds until it dried right back where I started.
Within about an hour I had done the lights on the van as well as those on my daughter's 1998 sedan. I had used less than one-quarter of the bottle to rehabilitate four headlights.I used the "Armstrong method" of application, that is, vigorous rubbing by hand, but it is a lot easier to use a suitable buffing pad attached to an electric drill.I  give this product five stars for effectiveness and value.
I've been searching for months to find a product to clean up my headlights and honestly, for the price, you can't beat this product!! My mother in law's headlights were so dirty that we didn't think it would make a difference, we used other products--this one, after two applications its like brand new! !I would highly recommend this product..thanks Meguiar's!! !
By the way, I just used an old cotton t-shirt to rub them out and an old cotton kitchen towel to clean up the residue,  The directions suggest an application pad and a terry cloth. Also, I only used about 1/4 of an ounce of this stuff. Now, I have an almost full bottle. Overall, I'm happy with the results.
This was a gamble on my part. Another miracle in a bottle promised. This has actually worked much better than I imagined. It removed the haze off of every headlight from heavy to light. Some took more time and applications but you could see a big difference in minutes. I used it to clean my polycarbonate motorcycle windshield with fantastic results. This was quick, easy and I highly recommend it.
