Would you like to take care of my car right now?

Hello together I call myself car care beginner 🙂 I have a black Ford Fiesta that has never been in the car wash road and also does not come 🙂 I have always only washed my car with Autoshampo with hand about every half year or if it was really dirty. After that I have leathered it and about 1 times a year polish of I think Sonax with such a comic nano sealing used but also quickly down. The result was a ch after the polish also not really nice when I think about the many work oh my God :-). I would like to change that now and hope you can help me. Think with the car wash you can not do much wrong now for washing will take a microfiber sponge and for drying also a microfiber cloth. Now how do I go on before what can you recommend to me? Have now read a little and if I have understood this I need at the n The next thing I would like to do is treat it with wax or with sealing only what is the difference? Would a nano-sealing of what you hear from time to time be better than wax or better good wax? Can you take the procedure for me, as you think it is right and also recommend what you would use to explain that would be really great of you and I would be It should not cost a fortune now but would also spend a little more money for good products and also a good result for my baby as long as the result is true 🙂 How many times would I have to repeat that? Before that many thanks for your answers MFG Marc
