Significant rust forming on my $1,000 Kahr. Please help!

Very gentle Flitz for surface rust or Kroil Oil and a rag for even gentler removal with a soak and repeat over several days, depending on the depth.

My worst rust experience occurred turkey hunting when I wrapped my Remington 1100 in camo stretch material that resembled an Ace bandage. It rusted immediately and sent me running for Cabelas nearly 40 miles from camp. Bought what they had, Birchwood Casey Barricade and after rust removal and a few liberal applications I was good for the rest of the week.
 
Is was wondering how conservators of the major collections, museums and galleries approach the issue of rust. Is there a unified scientific approach that is accepted by all or most? It seems there should a unified standard of care.
 
First I'd complain. Maybe they had a bad batch of finishing or metal and can fix it but only if you complain. I have had a Kahr P9 for like 20 years, it's my hot weather and workout gun, has been everywhere including near saltwater. Not an issue.

If not, then recoat as Zerodefect said. I /love/ NP3 but that's harder to get now (last I checked they didn't accept individuals anymore) but plenty of other coatings. Metal coatings, not paint. Cerakote et al is paint.


I didn't /quite/ see it but may have missed: NEVER use steel wool on stainless. Not just the shiny thing but it will leave microscopic bits of mild steel which will actively promote worse and different corrosion you can never get rid of. Bad. If you must do this, get stainless wool (they make it, should even be at the local hardware store) or just use a Scotch Brite pad or other plastic dish scrubber type thing. But also just oil and a soft rag might be enough.

In fact... are you sure it's rust. Lots of things can be brown, so I'd just oil and rub for a bit, see what comes off, and if it re-occurs. Since it's simply invisible to me in the photos, it may be something else.

Dear brothers, are we a little bit silly?

Rennaisance Wax is the gold standard for museum pieces. Johnson's Paste Wax works well, too.
 
There is a marine product I used on my boat in saltwater and use the same product on my guns. It is called Corrosion X HD. Spray it on your gun over night and then wipe with a rag. Repeat if necessary. This product is amazing. I found a pair of needle nose pliers on the beach that were rusted shut by the saltwater. I sprayed the Corrosion X and now I use them for fishing. They also make one specifically for guns but I've never used it since what I use won me over.

I fell into some fine stainless steel wool used for stuff around openings to keep mice away. I grabbed some when i couldn't find my brass wool one day and its amazing. When used lightly with oil it seems to skim off red rust and leave bluing unaffected.

Never tried that, might have to look for it.
