Hello,
The express way to apply some Swissvax branded sealant.Its a QD type product that leaves some protection. Its a bit like Z8 or Aqua Wax but needs to go to a dry car. It looks ok, good beading after the inital application.
Nano means its polymer based as opposed to Nuba based, in the Zymol range you might find that Field Glaze is its carnauba oppersite.
People have stated to use nano express on wheels, i use UQD on the wheels. Same reason; it stops the build up of brake dust so quickly and allows it to wash off easier even if you have sealed them. Looks good as well.
IS it worth it? Its cheaper with out there MF they supply and probably a better buy with out the MF as well.
