I would like to treat my car with 3M paint knete, but I have a few questions about how you do that… The car washing/ungrowing is not a problem in the SB washing machine, but where can I use the dough? You need a lubricant (soap liquor), which should be washed off afterwards so that you can apply the wax. Since the city “wet” car care on the road or in (building) plants has forbidden I can therefore not do this at home. In the SB plant, however, I don’t want to claim the washing box for me for 2 hours, therefore my question to you experienced car conditioners: How do you do that, where do you go, if you have to work on the vehicle longer but still water/soap in play? Without being ratted out by the neighbors or the law something against it? Or do you really have to look for an SB washing box operator, which doesn’t bother you that you stand around on its premises for hours? I hope I’m not wrong here with my question, “am new” Many thanks for any answers!
