I had my front wheel wells replaced due to cracks, per the TSB. I had heard of the poor surface quality issues and insisted that if the replacements looked like that, not to install them.
They installed scratched wheel wells anyway, claiming that they could not normally be seen, and therefore, the cosmetics were not worthy of replacement. F%^&ed up, eh?
If I were to do it over, I'd insist on inspecting them prior to instalation. Keep rejecting them until they either refuse to do the service, or they get their shit together and request a special order.
