Scratch Doctor Glass Scratch Repair Kit for Windscreen & Windows Glass Polish with Cerium Oxide for Light Scratches, Wiper Marks & Water Spots on Car & Household Glass

What a great product. I had the misfortune to have a wiper blade break on my cherished classic car in torrential rain on the M40. With no where to stop, I had no choice but to continue on and watch the end of the wiper work a 4mm wide scuff in to my windscreen along the full sweep of the arm. The scratches were deep enough that you could feel them with your finger nail. Convinced a new windscreen was required I decided I had nothing to lose and purchased the Scratch Doctor kit. I spent 20 minutes covering and masking off the fabric roof, bonnet, scuttle and any other parts I didn't want to get polish on, an important step if you don't want to spend a long time cleaning up afterwards. Once everything was covered I fitted one of the polishing pads from the kit to the supplied polishing wheel, put it in my cordless drill (it won't fit in an orbital or dual action polishing machine), applied a small amount of the polish to the pad and started on the windscreen. It is a SLOW process that requires patience and is best done in small sections at a time. When the polish started to dry I applied a small amount of water to the screen and the pad with a mister spray rather than keep adding new polish to the pad. I did the water 3 times to each polish application and it worked perfectly. It took 60 minutes of hard work to remove a scratch that was nearly 100cm in length but it was worth it. Under extremely close inspection you can still see faint traces of the scratch but they are invisible most of the time and can't be seen when driving. I still have 3/4 of the bottle of polish left after I'd finished. I was quoted £622 for a new screen, without fitting, so a couple of hours work and £20 for polish seems well worth it.

Needs a lot of effort, but does the job in removing the worst of the scratch. Found you can still see the scratch is some lights .

Absolutely rubbish dose not work very misleading description & pictures straight in the bin

Don't normally leave product reviews but feel compelled to do so given some mixed reviews on here. By using something I shouldn't have to scrape ice from the windscreen, I'd caused 15 scratches on the car windscreen. They were very visible from outside car but not really from within unless sun was hitting them at a particular angle. Followed product instructions to the letter and all scratches have been fully repaired. A couple of deeper ones were a little more stubborn than others so took a second attempt to resolve. The majority of scratches came out first time. I'd say all in all 45 mins of stopping and starting with careful polishing using a sensible drill speed. Have loads of the glass polish compound left over, and an unused polish pad in case I am ever stupid enough to scratch my windscreen like that again. Excellent product that likely saved me a hefty glass repair bill from a specialist. Also worth pointing out I'm not especially handy and I found the product super easy to use.

Tested on a car front windscreen with some medium scratches Pros: Nice packaging, british, It cut through wiper marks and fine abrasions. Cons: Connected to an electric drill and dialled down the speed however the adhesive sticking the velcro to the pad detached. The pad is too small. Left some deeper scratches in the windscreen

Very effective. I used this on a windscreen which had a huge scratch from a dislodged wiper. I used a drill and attachment which came with the set and it improved by 95%

Used as instructed on drivers side window. Spent 30 minutes and it didn't seem to make a difference. Might be good at removing some marks but doesn't touch the scratches on my car window.

Easy-to-use. Good job

prodotto valido, bisogna però avere perseveranza nell’applicazione sul parabrezza, sul mio,che era graffiato a causa della cenere vulcanica dell’Etna, ho rimosso gradualmente e con perseveranza moltissimi graffi create dalle spazzole.

Le produit a l'air pas mal bien conditionné et seulement aucune notice en français c'est là le problème quand vous achetez un produit en France ça serait bien d'essayer de mettre au minimum une notice française.
