Good day.

I should like to blacken my stainless steel gun. But my problem is that i don't know the type of stainless steel that Sig Sauer employs.

I should do it with Stainless steel Blackener gel. Because the gel will not run off from the pièces.

I shall disassemble totally my gun before to blacken it. Like that i shall blacken only the piece in stainless steel.

Because the barrel, all others pièces are in steel and in aluminium.

Hi Christian 

We havent yet come across any stainless it wont blacken so you shouldnt have a problem.

The best thing to do is try a sample in a discreet area first so that you can be sure it does what you want.

If you find it wont blacken you may need to etch the steel with a  hydrochloric acid /water mix to allow it to take.

Be careful at this stage as the hydrochloric can attack the steel if left too long.

Ideally i would strip the barrel from the action,clean,parts and blacken using the solution rather than the gel.

The solution will give a much more even black and far better results.

I would warm the barrel first as the reaction times are faster and wearing strong rubber gloves work the solution onto the barrel using a fine scotchbrite pad (Like a washing up scourer).

Leave to react for a few minutes rinse off and reaply as required.

The finish is only a surface finish and so will need protecting with a lacquer or wax to help prevent scratching etc.

Scratches can be dabbed in with cotton wool and solution at a later date to keep it looking nice.
