but still does work advice ...

I had scratches on my windshield due to wear my wipers. This product is for the final polishing. I started with a polishing paste diamentée (9 micron particles) and 6 microns and the final product, which gives the final outburst (particles 2.5 microns), all at the drill 2,000 rev / min. The result is breathtaking but know that it takes time, at three hours have passed. I replaced the included discs that I found too rough with a felt disc. I honestly do not know what would have happened if I'd start with this. Nonetheless, it is essential to buy it for a pin to be attached to the drill, the support ... for a low price.
