Before of course, why would you want to get brake dust all over the bodywork after you have cleaned it?
I normally do them whilst some wash&wax foam is soaking on the bodywork
this is the kind of thing that turns into an epic multi-page discussion on DW S). how can it matter whether you wash your car's wheels before or after the bodywork? use a different bucket and don't poor it over the car after you've done the wheels?
Forget having dirt from scrubbing the wheels splashing up your clean paint lol, stick with doing it the way you are!
always last. Why clean them and then let the dirty water from the bodywork drip all over them?:S
i use separate products and procedures. so i do them when i want to tbh. if i snow foam (which recently i do pretty much everytime) i will wash the wheels while the snow foam is doing its job. then spray off wheels at the same time as the snow foam.
