Well went to the dealer with my brand new tires and fresh powder coated rims and paid 209.00 for an alignment walked out with four scratched rims! What a deal. Still waiting on lr to get back with me they are trying to get me to let them use a paint guy to fix the rims.....not gonna happen.
10 years ago I would have exclaimed "wow, they did that" or "wow, they are then trying to treat you like that" but unfortunately now, it is pretty much what I expect now. Too many dealers have royally screwed up on my vehicles that I now don't let it out of my sight and I make doubly sure we are all talking the same language...in writing.
Anyway, stay firm about refinishing the wheels. It's total BS they would try to "fix" them for you. Ask if it's OK if you key one of their cars on the lot but "no worries, I'll have my paint guy fix it right up, good as new..."
The only way to do the wheels correctly is full re-do, meaning, stripped, and redo by the powder coating shop. No sanding, no grinding. no "fixing".
Mistakes can happen yes, that's why dealers charge what they do and have insurance for losses due to their own faults. Stay firm with an attitude of "I understand mistakes can happen. it's just business, you'll be needing to cover cost of place who did the finishing first to redo it".
