Hello, on the wax and non-wax preservations always stands for new or polished / prepared varnish. Why does this stand there? I don’t have time and in the cold I don’t want to polish my car either. But would like to protect it from the salt. Can I still apply a product such as SONAX XTREME Protect+Shine Hybrid NPT after washing. Will that also last three or four months until spring? If that is not possible, you can then easily and quickly contact me. recommend processing product? Greetings Chris
