raaizin- Welcome to Autopia! Sorry to hear your wheels got messed up.
Some sorta-random thoughts follow:
- Pressure washing Audi wheels shouldn't mess up the clear :think:
- Much as I like Wurth stuff, others here have been very critical of how their wheel paint holds up. No negative first-hand experience here though.
-I've never been able to do decent wheel refinishing. Gee, it just never looks as good (IRL) as all those "check out my work!" posts on the internet

And it's not like I'm all thumbs...
-My Audi dealer has refinished silver-painted Audi wheels to 100% perfection (and coming from me that's quite a statement!), so skilled people, using the right stuff, *can* do this job right.
-Just IMO, but I'm with
David Fermani on this, a nearly-new Audi deserves to have the work done properly even if it does cost a little bit.
