Brillent. Well done, that was me a few years ago. I do like white, and the i6, does look fab in the colour, with added gloss. Love a stormtrooper look. I did find on the white bmw, a rub of autoglyms, SRP, helped with any scrapes, and funny ingrained dirt, not just tar. Its old school, but may be of use during the winter grime. Back from hols now so gotta to grip with this machine. Have ordered from the sun lounger, a lower storage panel for the dssh partion, from Ali. Will let you know, how it goes.
Seen the storage panel on Amazon (and subsequently on Ali, for a fifth of the price lol) – let me know how the fit is, if it fits proper i’ll be ordering one too, my glasses slide back and forth in the partition, annoying.
For winter grime and general maintenance for now with the wax, i’ll be sticking with Purple Haze by Alien Magic foam and Autobrite Purple Velvet shampoo, then a quick rub down with Soft99 Speed and Barrier to “top up” the wax.
I will say, the shape of the car kind of sucks for washing. So many nooks and crannies. But, worth it – looks like a million bucks now. Also, just rained, of course, lol.

edit:
Also, after reading the Stormtrooper reference, the car is now called Finn. Can’t unsee it.
