Finish wears off - Guntec USA AR-15 Charging Handle with Latch

I wanted a different color charging handle to differentiate my AR builds. The red looks awesome at first but after a little use the finish starts to chip off. It is wearing in the expected areas where the charging handle meets the upper receiver; however, it is also chipping off on the upper right hand and lower right hand side of the handle. I use my left hand and to retract the handle so not sure how it is getting scratched or chipping off. At this point I will use this handle until all the red wears off and then just paint it.
