Hello, I’ve informed myself a little bit but I still want to get some more information. I know there are many thread on this topic but my phone calls differ greatly. I live near Osnabrück and I am looking for a company that seals my car hollow space and install an underfloor protection. I read prices of 200 400 euros again and again. I called some companies. They said about 3 days work with dry ice floi d film transparent several layers about 1300 Euro. With photo documentation etc. Everything is glued on and built apart. Now I am not a professional and have obtained several information. Do you have any tips or experience whether an expensive coating is worthwhile. I want to drive the car also in winter. With friendly greetings
