Costs for the revision of corrosion protection factory new motor vehicle

Moin, I’m getting an MG ZS EV as a new vehicle these days. I know that the corrosion protection is not so optimal in some places. Despite the guarantee, I prefer to do something myself, so as soon as possible immediately after the transfer should be reworked – so the ideal way Mike Sanders fat in the cavities, plus normal U-protection where it is necessary at the open places. Now I have requested a plant in the area – which estimates 2 days and 1,000 € cost. old me for completely covered – it’s not that a gammely car with plague has to be rusted out and so on. Does anyone have any experience with the costs here? I would have to get the fat into the cavities myself, too. Lance, compressor etc. is available, I can also heat up the stuff. But is then just a single mess on the farm. Andy
