I've got nothing against dodo but I would thoroughly recomend a sealant for white.
Sealants tend to fair better when transmitting colours as reflective as White. Colours that absorb lots of light (darker colours) benefit from the depth that a premium carnuba wax gives. Colours that reflect a lot of light rather than absorbing it (lighter ones, silver whites) tend not to look as impressive with a wax.
If your after that "wow that is fooking shiny" look when you step back and look at your handy work, then a sealant will do a better job. (oh unless you wanna spend 7k on zymol royale, that's pretty good on white)
so onto sealants I'd recomend.
Zaino z2 is great. Gaz commented on his car after I had detailed it and used z2 as a last step. He said it look amazing and looked like porcelain.
Another fantastic product is werkstatt acrylic sealant, and with that you can add to the finish with a sealant safe spray.
Sorry that was a ramble but I hope it helps.
