Your Opinion on Getting Robar NP3+ Coating on this Kimber Ultra Carry II
This Kimber Ultra Carry II is my nicest pistol (photo 1). I shoot about 150 rounds every weekend. The paint on the aluminum frame is starting to wear off at the main friction areas. I would like to have the frame coated in NP3 Plus Firearm Finish by Robar (Robarguns.com). I am trying to determine if the cost is “worth it” given the current wear on the pistol. The coating cost is $200 for just the frame, or $400 for a complete coating (including all internal and external parts and one mag). That's not a massive investment for me, but it's also not trivial.
My question is this: In your opinion, is there still enough life left in this pistol to justify having it coated in NP3? Is the wear in photos 3, 4 and 5 “normal” and nothing to be worried about, or is this type of wear problematic for significant future use? If I can get another 50,000 rounds through this pistol, the coating would be worth it to me (approximately 150-200 rounds per week for 5 years). So do you think there is enough life left to justify the coating? Leave it as-is and don't worry about the wear?
I know this is a subjective question here, so "opinion" is the operative word here. Just getting the general thoughts of people far more knowledgable than me about wear on Kimber Pistols.
