642 Airweight Finish flaking?

I bought the wife a Model 642 Air weight in stainless steel. It seems that some sort of flaking is taking place on the left side above the trigger guard. I don't want to pick at it, so as not to make it worse, but it looks like paint flaking. What could this be? Does this revolver have some finish that could do this? I've never seen anything like this on a stainless weapon.
 
Apparently these guns have some sort of coating that can fail. I had a friend who had the same problem with his S&W. I am not certain what causes the failure and why they would utilize it in the first place – seems to defeat the purpose of a stainless finish.
 
I have the same problem with my 642...............I say problem, not really, yes it flakes but it doen't bother me. This is my pocket carry revolver, I don't plan on selling it, its smooth and reliable, I don't care if it flakes or not. It doen't affect the functioning of the revolver.
 
It's a type of clear coat or something over the aluminum frame on the revolver. Give S&W a call if it bothers you and see what they'll do.
 
Flaking

I gave my son a Custom Shop 625 last year. Scandium frame has begun showing flaking after he soaked it in Hoppes #9 while cleaning it. Haven't heard back from him what S&W said yet. That stinks. Nothing anywhere about not using Hoppes on the finish.
 
The frame of your 642 is not stainless steel, it's aluminum. The flaking you're seeing is the clear coat. Aluminum requires a different type of finish than steel and it typically isn't as durable. The Colt Cobra that I used to have was very lightly used, but it had very obvious holster wear in certain places (the edges of the topstrap and bottom of the trigger guard). What type of holster are you using? A poorly fitting holster will cause more rapid finish wear than a better fitting one.
 
Don't rule it out...

Those frames with clear coat are susceptable to solvents. My son's 625 custom shop has neevr been in a holster. He shoots it infrequently and after shooting he cleans it and reurns it to the box.
 
I spoke with S&Ws customer service department about a customer's revolver that was flaking and was told it's related to cleaning solvents and S&W will evaluate for warranty repair on a case by case basis. I can say that none of the ones we have sent back have been refused warranty service, though.
 
I'm buying a 638 that has this clearcoat on it.

What brand and type of gun cleaner solvent should I use on it that is safe to use?
 
Use cleaners like Breakfree CLP or MPRO-7/Hoppe's Elite which are the safest on the clear coat finsih. Don't use Gunscrubber or other similar harsh degreasing solvents. Hoppe's #9 is okay as long as you don't soak the gun in it.

If someone has no interest in newer S&Ws, why would they even bother to post in this thread about S&W "greed" and to state their lack of interest in them. What a waste of bandwidth. I suppose they want a cookie for making their opinion known in a thread that did not call for it.
