While I was detailing my car this weekend I noticed one of my rims, Carrera 5 Spokes, was loosing its clear coat in some parts. At the same time I noticed one other was deveoping hair line cracks in the clear coat

The rims have never been hit and nor do they have any curb rash. Anyone ever experienced this before and I assume this is easily rectifiable.

 

It can be repainted. What do you use to wash the rims - sometimes wheel cleaner or abrasive sponge can cause this.

 

Soap and a towel, nothing abraisive every been used on the rims.
