PlastX Clear Plastic Polish Headlight Restoration Polish, 10 Oz

This stuff works really well and you can see the results right away. Great price, color and great quality that can last for lots of projects. Super smooth, great bottle size, smell good, and easy to use.

Tried the polish on badly mineral stained house glass windows because that's the only polish I had. A previous owner must have had a sprinkler on the one window. The house siding also has mineral deposits. Lots of issues here. This window gets full sun. The mineral stains were 10+ years old. The buildup was severe. Tried vinegar. Did nothing. It's hard to keep a window wet but I tried. Tried dilute muriatic acid. This worked well on the upper areas but not the lower streaks. Tried Meguiars polish on just one spot to see if it was worth trying. About 5 minutes of drill polishing nearly cleared it. Took about an hour of drill polishing but the large window and lower window are crystal clear. Used only a small amount as the bottle was nearly empty. Use on both cars yellowing headlights for years. Turns them crystal clear. Then add Meguiars clear coat. It's a bit of elbow grease but it works. Very useful product.

Cleaned it very well and easy to use as well and my headlights look brand new and very effective and clear

I have a Can-Am Spyder motorcycle. I JUST purchased and installed a new windshield that was not an inexpensive upgrade to this bike. As it happened, I large rock hit my plexiglass windshield at about 70mph and caused three major scratches. Distressed of course as this was brand new and then this happened. The new windsheild did its job however, and that is why its on the bike to begin with. I caught a glimpse of the rock and it was about 3 inches wide and hat that hit me, definitely would have caused a significant injury with the force at which it hit. Its has taken some effort, but it this product was quite amazing. The abrasive used is not too harsh so it did not cloud the plexiglass at all. Each time I used it, it wiped off easily and completely and I could see a difference in getting the scratches removed. The scratches are getting removed more and more as I use the product, wipe it off and repeat the process. The area around the scratches is also highly polished and I am thinking that I will use it to take care of even the smallest nick. Have always trusted Mequiars products and this one is no exception, especially for the price. I am VERY picky about that bike and what I use on it. This is a product that I will keep for this appliction. I am a huge fan of 3M products as well and that is my standard for judgement. Quite honestly, the 3M product I used for this application, which is also amazing...just got retired in favor of this product. As well, that rock also hit my fender before slamming into my windshield. Used this same product. Scratches on the fender are gone, like they were never there. Of course, you might want to try a very small area in an inconspiquous place, which you should do with any product that removes scratches, but I would wager you will find this is a fabulous product and will not harm or mar your plastic painted surfaces where the color is mixed in or on your plexiglass/plastics.

Worked well on my 27 year old convertible top windows. Quick and easy to apply

Mcguire used to have a two part system for cleaning clear plastic it worked much better. Although this one works ok, it just doesn't work as good. Just like anything these days , let's make it cheaper. I mean, it's a better price then the 2 part A and B bottles, if I remember right it was more expensive , but you get what you pay for and when you're trying to make something look better , I'd rather spend a little more money and have it work better. So I hope mr. McGuire's if you read this , just make the 2 part system again!

I never expected this to work but it was cheap and I'm lazy. So I gave it a shot and it worked great on my 2013 Honda with 250,000 miles on it. I did a quickie job and it looked good, then I went outside a few hours later to make sure it still looked good. It does. And I only used an old gym sock. I'll do it one more time with a little more effort to try for 100% better. I think it was totally worth it.

I used this to remove a bird poop stain from my taillight that did not come out in the car wash. Removed the stain in seconds! Worked so well.
