I used to do all the polishing work first before taking the gun into a gunsmith to re-black. This is where the costs are incurred because there is a lot of work involved and as a result I was able to get my barrels done for @ £45.

Have a talk to your local gunsmith and see if you can come up with a deal whereby you do all the dirty work and he just does the blacking, and see if he will do you a deal.

Hiya

 

You may want to investigate Blackfast on the internet.

 

Although not traditional bluing, as it is black, it is something I came across in an Engineering magazine as an alternative protective coating option for a whole rake of items/components etc.

 

It is possible to buy a 'kit' or get them to do it.

 

No experience of it yet noted it as an option/alternative when the need arises.

 

 

Regards

I tried it, and spent ages doing prep etc, but it did not last, I had taken my game gun on a salt marsh for duck after a walked up day (silly thing to do :lol: ) even a tiny spec of grease etc will screw it up, much better to let the smith do it, should be around £50-£75

The only problem with cold bluing is that it is not abrasion-resistant.

 

So, if you blue the ends of the barrels then it will very quickly wear off due to abrasion when you continually put the gun into the gunslip etc. It is OK for small areas that are not handled or, (should I say this?) if you are going to sell a gun....

 

The finish that you require for cold bluing is the same as for hot bluing - a very high mirror finish unless you want a matt finish. For a mirror finish you ideally need a buffing wheel, and for a matt finish then wet and dry or similar will suffice.

G96 Gun Blue - £9 on Flea bay.

 

Have used this for years for small to full barrel jobs and swear by it. The cold blue process will never be as hard wearing as the traditional hot blue process, but if done properly, it will last surprisingly well.

 

The main issue is, as with all things, the preparation work. The more time cleaning, polishing, and finally de-greasing the metal that is to be blued - the better the finished work.

 

Do not handle the work with bare hands during the bluing process and apart from the health and safety aspect, the moisture from your hands will spoil the bluing process. Always wear rubber or surgical gloves that have been well cleaned and de-greased.

 

If you do contaminate the work prior to completion, then just de-grease and start again. The final few coats should be applied with 000 wire wool, which will provide a mirror finish if the preparation work was up to standard to start with.

It is good stuff and I didn’t think you could buy it over here. It contains gold which is why it is so expensive.

i bought a blue pen last week and was trying it out today on the mossberg; all you have to do is degrease the area and rub the pen on. didnt work on the receiver (aluminium maybe?!) but worked a treat on the barrel and on the magazine tube; i bought a bottle of stuff for cold blueing a few weeks back but havnt had the chance to try it out yet, just had a spare 20 min earlier and thought idtry the pen, only cost 13 euros :good:

Slight hijack - apologies....

 

I was thinking along the lines of having a go at re-blueing the barrels on my SbS, but after reading up on the process etc, I know that a) I dont have the time and :good: it will go wrong and I will be in a foul mood for a week with myself.

 

So - can anyone recommend anywhere which can provide a re-blue service near Leighton Buzzard (Milton Keynes, Luton, Aylesbury, Bedford are reasonaby close by) - also anyone got an idea on cost?

 

 

Thanks all

Be careful when you get your barrels re-blacked especially if they are older ones that have be soldered together with lead solder. Some dealers will charge for an expensive blacking job and then simply hot black them which is not as good as cold blacking. Trouble is if you hot black an old set of barrels it can melt the solder.

It’s easy to see the difference as the hot blacked barrels will be a dull semi-gloss finish, whilst the cold slow blacked barrels will be a deep wet looking shine.

Hot blacking = £75.

Cold slow rust = £200
