Flitz Multi Purpose Metal Polish Liquid - 7.6oz Bottle of USA-Made Tarnish Remover - For Aluminum, Chrome, Brass, Nickel, Silver - Non-Abrasive Metal Cleaner and Polish, Restorer (1 Pack)

I have used Flitz paste tube previously for other metal-polishing tasks. It worked very well. I got green liquid version specifically to polish plastic. I have only used this "green liquid" version of Flitz 3 times. I also have some abrasions/marks on auto paint that I need to buff out. It is specifically advertised for that task, so I assuming it will work. Fritz has an excellent reputation when used as intended. So far, I had INCREDIBLE results on one plastic item, and mediocre results on the other 2. I am not going to knock any stars off, as the failed tests were not the intended or advertised use for the product. All tests were performed with a battery operated Dremel and a felt polishing wheel. I thought about starting with a cloth and polishing by hand. That may be a better way, particularly with plastic glasses. That said, it was faster with the Dremel. Probably take more care with the speed and heat generated to avoid melting/deforming the plastic. TEST 1: Red plastic/acrylic watch crystal on a vintage LED watch This was the reason I got the Flitz. I have a decades old watch with a nice red acrylic crystal that was so scratched, I could hardly see the small, vintage LED numbers below it. I applied the green Flitz liquid directly to the watch crystal and started slow speed on the Dremel. I then turned it to high speed. This one only has 2 speeds and since it's battery operated it is not extremely fast. I recommend using slower speeds on a corded Dremel. Again, heat may cause problems. I applied more Flitz 3-4 times. RESULT 1: The results were nothing short of amazing. The scratched, dull, hard to read crystal looks almost new. I am extremely happy with the results. See pics TEST 2: Plastic reading glass lens with pretty large abrasion and a small scratch So, I twisted my ankle several years ago and fell face first onto blacktop. My reading glasses lens absorbed the impact and created a large scratch/abrasion. I applied green Flitz to the lens and started on slow then went to high speed. I applied a little more Flitz 3-4 more times. RESULT 2: The white, almost opaque scratch became clear. (see pics) It is at least clear, but the area of the scratch definitely changes the focus/magnification of the lens. I don't know if I got it too warm, but it seems like the area immediately around the scratch is different as well. The shape of the scratch is definitely still visible. It is definitely MUCH improved, but I'm not sure Flitz is a good solution for plastic lens scratches. Then again, I have no idea what I'm doing. TEST 3: Plastic lens on black sunglasses. These sunglasses laid face down and got a clear "rub mark" that was about the size of a dime right in the main focal area of the lens. It was extremely annoying and made the sunglasses unusable. I applied Flitz to the lens and followed the process above. RESULT 3: The white/gray, nearly opaque abrasion is gone. However, the area polished is also a little bumpy/wavy. It is very clear, which is a huge improvement. However, it looks a little blurry when you look right through that particular spot. There is also a slight "halo" around that edge. Maybe that is a coating that partially polished away? (see pics) Again, this may be because I got it too warm. Maybe I used the wrong felt polishing wheel for plastic lenses. I definitely do not know what I am doing, so the less-than-stellar result may be 100% my fault. Did I mention that removing scratches from plastic sunglass lenses is NOT AN ADVERTISED USE of Flitz? SUMMARY: I am extremely happy that my watch is usable and the crystal looks great! (see pics) That was worth the price of the Flitz green liquid. If I can figure out how to make it work for polycarbonate sunglass lenses, I have a EXTREMELY scratched pair of vintage Gargoyles that I would love to restore. I need more practice and research before I try that project. ADVICE: If you want to clean up an acrylic/plastic watch crystal...BUY THIS. If you want to use it for any of the advertised and documented uses for Flitz green liquid...BUY THIS. It definitely works.

Certainly not a magic potion that suddenly polishes the worst of the worst, but with some effort, following the instructions, very good results can be obtained.

Having searched for long time to find something as good as this.

Kann das Produkt nur weiterempfehlen. Für Kunststoffe und Harze genauso perfekt geeignet wie für Weichmetalle. Leider gibt es das Produkt nicht über Amazon Prime aber dafür kann das Produkt nichts

Had some chrome rims that was neglected by previous owner and use this product came out like new after some elbow grease
