First of all: Neither Sonax still at Nigrin I was satisfied with the products. Whether cheap or premium, each time you had to play with the brush and on stubborn stains several times.
5 years ago I then get the hell rims between the fingers. High chemical but also highly effective. Here with us in the area difficult to obtain. My dealer had converted to Liqui Molly, so for 2 years in this application. I am highly satisfied why: In principle, the same result as better to the rim devil but a tick.
+ Removes baked dirt usually on the 1st application (assuming you washed with a pressure washer to!)
+ The liquid reacts with the air and turns dark purple, so you can see where you have already sprayed
+ Even the highest quality S-Line wheels from Audi through the stuff without problems
+ No nachbürsten necessary
+ Very good price / performance ratio
+ Cheaper than many Super Premium product of Nigrin or Sonax that not for nothing have ne enclosed brush
- Since chemical / sour cleaner smells that thing accordingly, but that's how it is. Since you do not constantly applies and then outdoors you can adjust it
