Hi all

 

on my 2018 superb 280  one of the wheels has started to blister and gone white on the raised silver area  (water ingress)

 

they have not been kerbed or damaged by us, and car is always hand washed etc.   

 

is this covered under paintwork warranty -?

Providing there is no paint or lacquer damage then yes. 
 

Take a hard look for stone chips. 

Hi - it probably is the lacquer that has lifted and water has got in underneath
