I once owned a 6.5 " Washington State Patrol gun that experienced the same treatment on the grip. One could still make out 5 or so letters that weren't totally removed. Mine shipped to a different wholesaler in Seattle.

Thanks for the fascinating post. Your efforts go way beyond the norm and are appreciated by those of us who love tracking the history of the guns in our respective collections and now, thanks to you, get to look under the hood of the process.

I have a 2022 Highlander Hybrid with the turbo 4 cylinder engine. I only have 13,000 miles on it but all seems fine. I'm averaging just under 34 mpg so far.
