I knew this would happen

Seconded. I own an impact, and NEVER use it to install lug nuts, plated or not! Torque wrench only.

I learned my lesson when a tire shop stretched every wheel stud on my old car. True, the studs weren't the standard size ("normal"), but it was an unnecessary waste of time and money to replace them all.

i stop using impact gun the day i work on my Fairmont and per my Neighbor who is a mechanic put my wheels back when for a drive and felt the steering wheel stitch , when igot to my friends house i asked him what it could be he noticed one of the lugs was loose i was like never used an impact on my car again just dont trust them. now even if the tire shop uses an impact on any car im driving i still check them out with the tire iron, more then once noticed a couple of them loose...

I won't use an impact either. In fact, every time I've gotten a flat I've taken the wheel off and taken it to the service station either in another car or put the spare on the Yaris, just to avoid the over torquing that the monkeys in the tire change shop are likely to inflict on my lugs. I'll trust them for a mount and a balance but that's about it.
