With great expectations, to bring the spotlight back on the Micra glossy, I have made myself then under a cloudy sky (one should not apply the polish under sunlight) to work. According to the very clear instructions (included with in several languages) I generously but kleinfächig applied the polish in the appropriate places on the headlamps and -according the Manual- incorporated vigorously with a cotton terry cloth and the appropriate places powerfully with the polish grated. This process I have repeated several times. Sorry, could be no change at all, let alone to improve the pale impugned Make notice. The instructions I have read several times in order to avoid that I have possibly made an application error. I then tried it several times to several affected areas in the headlight glass in the same application. Also in all other places I could find no effect. I then tried to dry the polish by the generous application (as you know of car polish) and then rub vigorously. This attempt also remained absolutely ineffective. The pale attacked sites on the headlight glass of Micra remain there still stubbornly despite the many exhausting attempts.
After about 3-4 hours of unsuccessful procedure - I really treated all sites at both headlights and even achieved at any point the slightest success - I have resigned then canceled the project "Renewal of the headlight lenses".
I do not know what kind of acrylic glass have treated the reviewers who have given this product 4 and 5 stars. I also have no idea if there are different types of acrylic glass. I just know that I have blond and blue eyed believed the advertising promises of the manufacturer that you can put each acrylic glass in an almost new condition with this polish. This does not reflect that. This polish unfolds on acrylic glass (at least for the acrylic. From the headlights of Nissan Micra are made) the same effect as water. Namely no. The main difference is that 296ml of water as opposed to this polishing cost next to nothing and this polish in contact with skin it can dry out. Otherwise there are no differences.
The product is therefore absolutely overpriced because there is no - has effect - but actually no.
This product I would actually not therefore repeatedly awarded a star due to the mentioned own absolutely disappointing experience. I have never given a 1-star rating on Amazon and I thank all reviews always endeavored objectively and fairly assess. But this product would I actually get a 0-star review, since it finally shows also 0-effect. But 0 star review goes here not (you have at least 1 Star = "I like not" forgive). A return I saved, since the bottle already dawned and the majority of the stuff (it's just stuff - the name polishing does not deserve) is consumed.
I highly recommend this product, therefore not recommendable.
