New rims
Can't beat that time when the rims are box fresh.
This is a unique opportunity when they're spotless to keep them indoors, wipe down with ipa and apply Gtechniq C5 wheel armour at your leisure in the comfort of your own home.
Then buy some C2v3 (which is dead cheap and easy to use) to top it off.
I did this about 6 months ago on my daily used Zed and all I clean with now is shampoo.
I use the C2v3 on the bodywork as my LSPand occasionally on my rims too.
It's like water.
Spray.
Spread.
Buff.
Surfaces don't even have to be bone dry which is a bonus when topping up slickness to he rims.
