    Selective Plating Copper

    Pedro Newberry · 0 · Posted

    I am wanting to plate my 3.3 Gallon HD Sportster gas tank - externally only.  I was wondering if this process will work?  Is the surface area to great to maintain the 4.5-6v needed to apply a nice copper coating to?  Also, what would you recommend to clear coat it with to maintain the luster?

    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

    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.

    Do Caswell plan to offer the mini tank sealer product with the same colour options as the GTS1750 product?

    Bel Reeves · 0 · Posted

    As per the title - do Caswell plan to ever offer the mini tank sealer product with the same colour options as the GTS1750 product?

    The clear product is good but it it is far easier to see if the coverage inside a tank is good if the sealer were coloured.

    If unopened Caswell Tanks Sealer has a shelf life of 24 months, if it is opened, that reduces to 6-8 months, this is based on it being kept in a building and not outside

    GTS1750 on XPE plastic tanks

    Martin Kasche · 3 · Last reply by Clare

    I just got the XPE tanks of my KTM 660 Rally coated and one of them is standing in the living room filled up with 5 litres of fuel for 4 weeks now. I found one blister in the coat already. So I now know I will need to seal all tanks and my coater needs to repaint this one tank after leaving it another 4 weeks without fuel to get the settled ethanol evaporated. The other tanks are empty for more than a year now. I just have some questions here:

    Cleaning the tanks: There is written about diluted

    Nickel plating a copper bath

    Ally · 1 · Last reply by Clare


    we usually gold plate various items using brush plating method.   We want Nickel/colbalt a copper bath.  We have experimented a few times but failed.  We need to use the brush plating method as the object is too large.  Will these chemicals be ok for brush plating? ELECTROLESS NICKEL/COBALT CONCENTRATE PART A, B, C is this for tank plating only?  I have done some tank plating a few years ago very successfully.   Will the NICKEL CRYSTALS WITH BRIGHTENERS be ok for brush plating?

    Dear Sir/madam,

    I have read your product "Nickel anode" and its weight is 1 kg. What is the dimension?

    Do you have Nickel anode with 6" x 8" dimension or less? I need it for my PhD work.

    What is the purity of this product?

    Thank you

    Kind regards

    Hi, I have two tanks, one 1.75 gallons and the other 2 gallons so 17 litres. Being a cheapskate I just wondered if I could get away with a mini kit to do both?

    1955 Chrysler C-300 twin carb restoration.

    Tim · 0 · Posted

    Hi, I've removed the twin four port Aluminium carbs off of my 1955 Chrysler C-300. They were gummed, seized and in a pretty bad way. I've cleaned them in a ultrasonic bath with an Oxidation and Rust Removal Ultrasonic Cleaner Solution and then blasted them with walnut shell to remove all of the old tarnishing, however so they stay looking good, I wonder what you might advise to either plate them with a protective zinc or anodising. Thanks
