Marushin golden Luger --> black finish?

Hello!

I have a marushin golden luger, like the one on this picture:

The reason Marushin made these ones gold is that it is illegal in japan to make a metal model gun looking like the real deal.

Anyways, it is an excellent replica, really awsome! Nothing rattles or glitch. It is top quality.

Now for my question.

Do any one of you know if there is a way to make it metal grey finish like a luger should look, chemically somehow?
I guess the best way to go about it is to try to remove the gold layer for best ageing. I don´t know what kind of metal it is but it feels much harder than zinc/zamak. but it´s some kind of alloy.

I hope some one has an idea. Much obliged!

EDIT: I am sorry for any bad english.

Thanks / Jeppo

Yay! Another Swede! Welcome! Oh, and PM sent...

I never blued any model, but many folks here are quite experienced :-)

8ace can certainly help you, as he already blued his Luger:

There is also a discussion on removing gold from metal models:

Thanks guys!

OMG! 8ace's luger looks absolutely great!
Now I HAVE to try this, just need to read up on a thing or two.
Right now I have no place where I can do this so it´ll be a while until i can post the pictures of the result, but I will, I promise.

I think I will try to find some cheaper model to practise on...

Thanks!

Definitely find something else to practice on :-)

Even if it will be slightly different material, you will get used to the process, get reference point and learn what could go wrong ;-)

I is amazing how many things can only be learnt from practice... I used to think that many tasks such as cutting wood or shaping metal depend only on having tools. How wrong I was!

Yes, I must have a practise round on some thing. You are right, you learn a lot practising.

Right now I have a hard time removing the gold layer. I am using a scouring pad but with poor result, nothing is happening...
I am afraid if I add to much force I will ruin the chrome layer?

Hi Jeppo, try some fine steel wool to remove the gold colouring.

That's what I did on my Kokusai revolver, and it worked fine.

Thanks!
I will try that. It´s not to harsh then?

I wish there where some kind of solution you just could leave it in over night and in the morning it was gone...

If you are a little worried, then try it in a small place first where it wont be hardly noticed.

I play around with cars all the time, and sometimes if chrome parts are stubborn to clean, I rub it gently with fine soapy steel wool. I'm certainly not going to damage a classic car if I thought it was too abrasive.

Give it a try, but do it in an area which wont be noticed first.

But it's going to be blued afterwards.

Very true, Cerwyn. I'm planning to re-blue a couple of model guns, and have been toying with this product, with great results. The method takes a lot of paper towel and elbow grease, but it does remove the blueing.
Autosol also makes a blueing remover, haven't tried that though.
