I used it for polishing aluminum (set of 4 wheels).. Of course, depending on the condition of the aluminum, it requires a lot of good preparation with sandpaper.. from coarse to fine gradually with water. I admit that the shine surprised me positively, although after the third wheel it didn't work as it should and needed more passes, but overall I was left with positive impressions and I will buy it again.

It requires many turns and when you do it, the soft brush dissolves. It takes a lot of effort to make it shine, a similar wheel with other soaps was much better

Polishing aluminum relatively easily. The hard brush with the brown soap brought it to a smooth condition and then the soft one with the blue for the final finish. Just be careful, it requires a drill with enough speed, around 2000-3000rpm. Otherwise, it will take a long time.

Crap guys.. The polishes were like bricks, they didn't do any work as if you were rubbing it with a stone... of joke quality, the whole set is not worth even 10€...
