Sonax is a large German chemical manufacturer with a genuine dealer programme in Canada, which makes it one of the easier brands on this shelf to get in quantity. The Profiline range is the professional tier; the consumer line sits underneath it in the same bottles with different labels.
The standout is the wheel cleaner. Sonax Full Effect is the iron remover most people encounter first, and it earns its reputation. The polishes — particularly the Perfect Finish and Cut and Finish pair — are excellent and considerably cheaper than the equivalent Menzerna step.
Sonax’s difficulty is range confusion. The same chemistry appears under Profiline, under the standard line, and under a Xtreme sub-brand, at three prices, and the differences are not always meaningful. We list the specific SKU and size so you are comparing the same thing.
