Amazing product removed wiper blade scratch with the drill attachment great to clean mild scratches good price one thing be aware when adding water it can splash onto other things wipe off as it dries on but still a great product

It tuke me a while to find out how to operate and get to the point , I had to go all the way untill paste gets dry then magically begins to work , I erase long deep scratches in a very short time . Happy for the result .

I had a screen with loads of wiper scratches. Very disconcerting at night, but at £800 not really wanting to replace it.I spent about an hour yesterday and the results are dramatically improved.Couple of caveats:1) Mask the rest of the car. It's not *very* hard but it's not fun getting the splatter off the rest of the car. I'd suggest all of the roof, rear screen (if you have a coupe like mine) front doors and bonnet.2) Take your time.3) Make sure you keep the paste wet. You really don't need much. I figure I used about 1/10 of the bottle, and one of the pads.4) Forget the cloth supplied if you're doing a large area.5) The scratches I had were very shallow. You couldn't feel them with the fingernail test. Larger stone chips I have are not removed. They *seem* to be reduced, but are currently shown into relief by being full of cerium oxide, which is white. It's faiding out already, though.6) While not perfect, *seriously* good improvement. If I look for some of the larger scratches I can see them, but I get as much reduction in visibility from smearing in the wipers.In general, recommended.

The recent sand blown from the Sahara (early April, 2014) left a grain on my windscreen which the wiper then gouged a 20" arc into the screen. It was distracting in the sunshine, less so in the shade and could not be seen from the outside. I rang Autoglass who advised that insurers would see this as 'wear and tear' and would probably not be covered by my windscreen insurance. I disagree, another example of poor ethics from that industry however rather than retaliate with my own poor ethics (put a stone through the screen) I researched a product that might fix it. This product had generally excellent reviews. One review that complained that the initial application of the 'coarse' abrasive further damaged his/her screen must have been reviewing this product in error as there is only one pad (plus an identical spare) and the liquid so there are no graduations of abrasive. I can confirm it IS hard work and took me an hour to clear the 20" scratch (which has almost entirely disappeared - just (barely) visible in a couple of places but if I'd been concerned, another 10 minutes would probably have cleared even these.Three tips:1) I put a band of tape on the inside of the screen (to mark the scratch) so I could see where to polish from the outside - it would be very hit and miss otherwise and take even longer - clearly this only applies if there's a specific areas to be mended rather than an all-over clean up.2) Follow the instructions regarding the use of water. It not only keeps the screen from getting hot (which I assumed was the reason) but significantly reduced the effort to keep the drill where it was supposed to be (it has a tendency to wander).3) I started with a cordless drill (against the advice in the instructions). It was too slow and the battery ran out well before the job was completed.

If a toothpaste can remove the scratch on your windscreen, this one can also!There is a very light scratch on my windscreen, and after 1 hour of polishing, nothing changed, and it is the same as before!

All Ok!

Literally worked as it says. Got all the scratches out my windscreen, they were very shallow from the wiper blades. Worth every penny. Took me a hour or so with just a drill. Used on my Porsche Cayman!

Definitely works! Takes time and patience but it works! It fixed a problem I caused!
