PSA Bluing definitely wears off

Opted for bluing instead of cerakote since I like the finish on Gen 3 Glocks. Got it cut through Wager and the cut was perfect but the bluing definitely needs to be reapplied after a year of being cut. I do live in a very high humidity area so that probably doesn’t help. No damage to my RMR since I had a sealing plate installed, but there was rust on that as well.
