Silky Shine from ceramic coating on rims is gone what to do?
Hey guys, rims had a really nice shining not to glossy after ceramic coating. Since then 4k km. 8 month and washing just with shampoo without rim cleaner. Now the shine is gone away.
What could it be? Coating already gone or is it maybe something other on the coating. What can I do. Which rim cleaner ist Pccb Ceramic Brakes safe? thx
