After a few polishes from different manufacturers (eg the Sonax Xtreme Polish & Wax 3) I ended up at Meguiars Ultimate Compound. So far, all polishes filled the Kratzerchen only or covered them what their recurrence after only one or just a few washes warranty lies ... and was always very angry. Ultimate Compound, however, drags right (to 2000 wet sandpaper tracks disappear definitely've tried to clear glass headlamps) and removes small scratches permanently! I tested thus far the driver's door handle of about 9-year-old Metallic blue-gray Skoda Fabia (all fingernail / ring scratches went away! How bad that looks certainly knows each) and my 11 year old Opel Astra G (silver metallic). Scratches that can be felt with a fingernail when hovering, but most still go out with one machine (or application of Nasschleifpapier). The result was startling good total for a hand polish with a slightly harder "lacquer cleaning sponge". I regret to have anyway not herumgeschrubbt almost 2h on the paint, the result was worth the drudgery;)
The pads like here in the video are mE too soft to be able to really break something. Sometimes revealed by 2malige application nor an improvement in earnings. On the glossy polished surfaces are all. I have the polish rubbed until it started to qietschen on the paint or white film was only dimly seen, then removed with a cloth (this must be very strongly rubbed so that no traces remain). A little guide is also top on the bottle.
I recommend this product to anyone who is thinking about a polish to the scratch to buy! By then become necessary sealing has indeed duplication of effort, but the result makes up for it!
