I didn't take any pictures for the simple reason that if someone really didn't want to believe me, pics wouldn't have done much more to convince them. The fact that I applied 4 products on different quadrants of the wheel, someone with butthurt could easily just say "you spun the wheel and you're saying sonax sux cuz yo hate them y0" or something like that. Yes, all products tested on the same wheel, each in their own corner. As for products mixing, I taped off the sections and put a towel over the rest of the wheel to keep most, if not all products from touching each other. Note: I will be trying Sonax again today vs. the Zep on regularly maintained wheels on a 2008 BMW 335xi. I will also report back. This SHOULD have pictures as I will not be "splitting" wheels for both products, each will get their own wheel.
