I use the Maguires ceramic liquid polymer spray , £38 expensive but very very good ,
I use on every bit of trim and on my wheels applied with a cloth,
like your comment said water just beeds and the bike looks amazing and smells nice aswell !
detailing products have moved to a very high standard these days - about time !
I use AutoGlym Polar Collection for 'regular' washes - you have to be careful of using the Polar Seal on anything you need to grip but for everywhere else its great, easy to use and doesn't cost a bomb - but then I don't tend to let my bike get real dirty - I can imagine if you commute you might want something a bit more hardcore.
