DIY wax/sealing with best service life for many motorway kilometres

Hey! I’m pretty familiar with the usual paint care or treatment program and used to use Collinite 476 in the past. After I currently cycle down many kilometers, mainly on the highway I would like to have something with more service life. Optimal would be a means that can also run off wash roads. After I have neglected my 3 year old Super-B for the last 6 months, I would like to go through the full program again. Large garage is available n. Can anyone approve my program again and recommend me a seal that corresponds to my driving/use profile? Wash thoroughly Kneading paint cleaning with machine polish (1-2 steps) Sealing (only which ones?) As I said, after I do many kilometers and not have all the time in the world, the later use should also be as straightforward as possible, as possible suitable for washing roads without having to move back with details in every small spot….
