Blue retouch - not a complete refinish

[Lightsped]

I have a H&K P7 PSP that is in good condition. I like the slightly worn out look of its finish (on the edges). However, there are two or three spots (left side of slide where text is, and top rounded part of slide) where the blue is really worn.

Is it possible to retouch the bad areas so as to make it look similar to the rest of the gun?

Who or what product does this? Can anyone recommend a blue retoucher in the Atlanta, GA area?

Thanks

It is possible to touch it up and make it look fairly good. However, the touch up will wear off fairly fast in carried in a holster.
Any of the better cold blue products will work. It will probably be noticed if you look at it closely, but it will look much better. I use a product called Formula 44/40 instant gun bluing. It works pretty good.
Good luck.

I won't be carrying this particular gun. Tell me more about this "cold blue" stuff. Is it like model airplane bottle paint or what? Is it easy to get on so that it maintains the smoothness of the finish?

Cold blue oxidizes the surface of the steel like factory hot blue, only less so, you might say. Degrease the surface, warm it with a hair dryer, and the cold blue will darken the glint. Blending in on the odd H&K alloy is a matter of luck.

I know of no more effective retouch, and a reputable shop would not claim to. A disreputable shop would charge you twenty bucks for a dime's worth of cold blue.

I would apply some cold blue and see how it looked. If you did not like the appearance, you would be in line for a complete refinish at some expense.

Vans gun blue from shooters solutions is the best touchup blue our shop has ever used. easy app and easy match.

This is the process recommended thus far:

Wear rubber gloves.

Degrease the area to be blued. (Birchwood Casey Cleaner/Degreaser.)

Use blow dryer to heat specific area. (Heat gun would even be better.)

Apply Brownell's Oxpho Blue with cotton swab or q tip.

Allow to penetrate for a minute, keeping area wet with bluing compound.

Neutralize with neutralizer from Brownells.

Repeat two or three times.

Apply Breakfree and buff with very fine Scotch Brite (000). (Note: I have not been able to find any other than "heavy duty" Scotch Brite.)

Apply more Breakfree and allow to sit untouched for 24 hours.
