I have tried several products on mine,and for my taste the Gtechniq EXO looks the nicest,wax depth with seatant shine,more Hydro something .. whatever,feels more silky and anti static than some (blackfire,tough coat),
Not real budget price but cheap enough at £50 something for 180ml, but one can do trims,glass,exhausts ect with it so saves a bit on other product which makes it better value.
Only caveat is panels need to be warm for application,so unless you are Bruce willis its more than likely there is a hair dryer somewhere around the house, and snow foam is now a waste of time as it dont stay on long enough to be effective.
As with most other Gtechniq products keep well away from the windscreen,that is unless you like a smeary wipe from juddery blades.
Oh and a healthy coat of Iron X works wonders on white.
