I am working on a pair 0f 520 rims.These are the wide rims and I am noticing that of the 3 pairs I have in the shop all have an off white base coat under the silver.None of the 7.5 rims I have prepped for repaint have this under the silver.It wouldn't matter to me but all of the wide rims have the silver flaking off.These wider rims all were produced after WH went away from off white wheel paint.Do you guys have any thoughts on why they did this?
