Better value with 13 Oz. I like the results. Use it for most outdoor plastics. Car headlights too.I have an 07 Camry. It definitely cleaned it. But not completely. The insides of my light assembly went from 60% visible to 80% visible. I didn’t buffer it tho. Seemed to run out fast. But I applied it about 10x to different vehicles and got the same result.ExpensiveA little pricey but the stuff worksCleared up some dull headlight lenses on 2010 prius. Looks better.This product is great. I use it on a plastic atv windshield. It protects the windshield and also fills in minor scratches. I also use it to clean my plastic eyeglass lenses. It is the very best eyeglass cleaner i have found. It also fills in minor scratches.The more one uses it, the clearer the lenses become. Its a little expensive, but so are windshields and eyeglass lenses. I suggest that you buy the bigger spray can. An amazing product.Use this for cleaning motorcycle windshield and there is simply no substitute. It may seem expensive compared to other product prices, but its the only cleaner I have found that doesn't scratch or leave swirl marks over time. My 2yr old aftermarket windshield still looks new even in direct sunlight. It has helped preserve my high dollar shield so in my opinion the benefits far outweigh the cost.If you want to keep your headlights and taillights from fading, due to COVID if you have plastic dividers in your business and want to keep them clean and streak free this is what you need to use. Make sure you also use a good microfiber cloth.
