 What's the best product to use for re-bluing screw heads and covering spots on firearms?  All I can find are kits with multiple bottles of bluing.  I just want to fix some screws that have been abused, and maybe cover a rust spot here and there.  Thanks.

I use OxphoBlue from Brownell's.It's easy to use and gives a good finish.I used it on a Colt New Service that appears to be a suicide gun from the bluing damage and was able to blend the repaired finish in to match the original.

,,, for smaller steel parts that don't need to be hard a simple blueing technique is to just hold them in a flame until they turn a nice blue ...... don't go beyond blue ...

pre-polishing is good .... you can get a very nice blue ....the blue is not very deep but then neither is cold blue ......   if you prefer cold blue oxpho is good, and heat the parts to about 120 F. and if small enough soak them in the blue in a cup for 30 seconds . ... after either heat or cold blue be sure to oil immediately.

If you want a dull black rather than blue, Birchwood-Casey aluminum black gives a dull black finish on steel similar to Parkerizing.  I find it more useful for blacking iron sights, etc.

Thanks. I think I'll try that oxphoblue. I wasn't aware of that product.

FWIW:  use degreased 4/0 steel wool to apply oxpho.  Dunno the chemistry involved, but it "bites" more and gives a darker and more even blue.  Also works well when using a "rust blueing technique".

had great results from oxpho blue paste as well.  For scrubbing rust and blemishes, I recommend Eez-ox and Brownells Stainless Sponge.

PS:  I would NOT use steel wool.  The Brownells sponge is much better imo.  Does not remove the bluing like steel wool will.
