Aside from fleet washing, even doing your own vehicles is more about what your starting with and how often your maintenance schedule is...Doing a tad more often helps me heaps as far as time and end result on my own cars. Sorry can't tell you brand I used last as I emptied the fiver into a couple gal jugs after a bit of use. Think it was called 'touchfree car wash' but who made it I don't know. It sure does downstream well and does same as yer after in way of a full service product. Lasting forever too..was an ebay item actually so maybe they sell on there all time..
Personally I start my vehicles off right though before using anything in the way of optical brighteners. I remove oxidation and machine polish with the Mcguires Deep Crystal. From there on in stuff just rolls off when washing with anything and then every so often you remelt the polish with the 2-butoxi type cleaners or add more polish... If you go with them fancier newer polishes with all the fancy additives or silicone stuff you never know if the remelt or new polish will work is my feeling. I'll stick with carnauba wax.
