Winter party questions?

Hey guys, I’ve had a new car with white paint since October. Now I wanted to make the vehicle a winter party and wanted to briefly show if this is okay: 1. Wash the car thoroughly in the washing box. Without wax from the lance of course 2. Dry the car properly 3. Apply Per Cleaner Wx for pre-treatment. 4. Wearing Collinite 476 S I have to wait between points 3 and 4 or I can start right away. I think it’s a new car I can use. I have new Alsu on it for my winter bikes. Do I also have to protect them and if so with what? Since I don’t have too much idea yet, I am looking forward to your answers.
