Are you all winding me up? lol
It's flat white with no lacquer. The most reflective and purest paint there is. If there the qualities you like about it, then you don't want to put a light absorbing wax on. It's not meant to look deep, although it can do if you use a yellow wax such as most carnauba. That probably means you didn't want a flat white car though, because your changing it. Hardly noticeable on colours, but not ideal for making the most of a white car. Flat white non lacquered cars are separate from coloured cars when it comes to products. If you want the white to stay white and to stand out, you want very little on the car. Then it can be blindingly white. Around 93% reflective.
Mr Sheen is my product recommendation. It's a degreaser with high silicone content. It will lower reflectivity but that light capture makes it look more shiney than it actually is.
I used to go mfn every week. hundreds of cars. It was well established that robs car shined the best. Dusters would slip off it. Product heads would spend hours getting near the finish he got in a few mins. Only stopped from using robs product them self's through internet scaremongering. It's safe enough for high grade furniture though, it won't hurt paint. It even says so on the can.
Forget everything I have said now. Just get the stuff from under the sink and try it somewhere inconspicuous. Judge for yourself it you like it. It's no hardship.
