What was the problem with us? We have a white T5 bus and on the driver's and passenger side and on the bonnet, actually in many places were small but still barely visible rust sites. We looked around a bit on the internet and then got stuck in the clay bar. The actually mostly positive reviews made a good impression. So ordered and a few days later the postman came with the product. The weather was good today so we could get down to work. Only the car was washed by hand to remove the coarse dirt. Unpacked dough, sprayed the bodies with the lubricant and quite simply the bodies rubbed with no pressure with the dough. Already soon the first flight rust spots have disappeared. With a T5 you can of course imagine that this is something more area already, as for example in a KA. With a microfiber cloth and clear, warm water we wiped again the blue has become by the friction lubricant from the car in order to see to see if there's something else.
The dough was enough for the whole car and it's even a small piece left (possibly for small improvements or if we have missed something). It took us around the whole car to escape from the places about 2 hours! The paint acts after treatment some butt and also has traces, but a little polish / wax layer then the car can not after treatment with the clay well damage. This follows but only in the next few days.
I would buy this product again and again and also recommend definitely. Even the dealer provided the means quickly and reliably.
Only the fingers are somehow then blue, but with a little face and a hand brush and this issue is resolved :-)
