Collinite 476 looks awful on all cars. It is a winter wax at best. 845 is pretty good, but again, not best on looks. SuperNatural will last a heck of a lot longer than a month, so application once a month is not necessary, as it is a waste of wax.
If you can't get out to top up the protection on your car as much as you'd like, a sealant is the way forwards, such as Jeffs Carnauba Spray or Chem Guys Blitz. Look for a Carnauba based product, Geddes, as it will look superb on red. Try and stay away from Acryllic products such as Jeffs Acryllic Spray as it will not give as good a finish on colours such as ours.
