Forced patina techniques.

    I've got a project on that I need to set apart from others.

    I've got there steel boxes -

    5-off them will be held in a fancy curved frame, made from oiled mahogany. (actual mahogany, not sapel)

    These are the steel templates for the ends to give an idea -

    The whole thing is to mount fancy electronics in. It's a functional but also artistic job.

    Now the "standard" way to finish these is just to powder coat them in black, but I'm looking for something more special.


    What I'm toying with is some sort of forced rat-rod style patina. But then I'd want to clear coat it over. I'd want it fixed, not "evolving" (ie not continuing to rust)

    I think that a bit of red on the steel will blend in the colours with the mahogany ends and make for a quality and interesting job.


    You can get patina via rust then electrolysis, but it's black / grey, and I'd like it a bit more red.


    So there's the background.

    So, two things -

    A) does anyone have any general idea
    B) clear coat over rust. Is that going to work in any way at all? I'm talking light rust, and not flaking, but clear coat is supposed to stick to base - I mean it's not a primer!

    So what would you do? Again it's a artsey job, and I'm after technique, rather than subjective "rat rods are stupid" comments! : )

    Thank you.

    Don't know if this will work but....

    Chuck come off cuts of steel in a bucket and lightly water with a watering can every day ( this may only take a day or two).
    Then lay the panel on a flat surface and pour over the rusty water and leave to dry.

    Clear coat the resulting effect (hopefully not a mess!)

    I've done waxed stuff before, and it's fine, but I don't want to force upkeep on the end user.

    In my head, I'm seeing a glossy clear finish with the rat finish under.

    Kind of like it's been vac packed?

    We used to paint it red/orange/brown camouflage first kinda pattern.
    Then the top coat and then scorched areas to break through and re show the reds for worn rust spots.

    Then lacquered that.

    So completely fake - ie all paint, no actual rust?

    I suspect I can get the rust easy enough. I thought a dip in a caustic soda bath to take everything back to metal, and then a dousing in somthing like vinegar would do it pretty much instantly.

    But then I need to get something over the top of that.

    You can even get vinyl wrap in rust effect

    I know someone that buried his cars wing after stripping the paint off it and poured milk over it. It rusted in no time

    So there are loads of ways to get the patina.

    But again, I think the real question is, will clear coat go over it reliably?

    What specific products should I be going for? And any application tips?

    Had a quick look. Looks good in the photos, but the one I saw was £100 for 5 sq MTRS, which is probably half that on an awkward shape, and I fear thats quite a lot of cash Vs some vinegar and clear coat?


    Have you used any yourself? If so, can I ask what brand? And did it work out nicely?

    A long time back we made some steel railings and the chap had them wet lacquered. It rubbed through in no time on the hand rail

    So he had it powder coated in clear lacquer and it was lovely and smooth but had the finish your after

    calcium chloride, mixed in water, normally comes in flakes, its used for fast drying concrete Without reinforcment, no doubt some will tell of the disasters with flats collapsing years back when it was used with reinforcing steel. need to nuetralise with plenty of water after use though.

    It's an indoor device, used to house electronics. I find that wax needs renewing even from general handling. In my experience, which may, or may not, be accurate, oiled wood lasts longer than wax on metal.

    Either way though, I'd like a fancier finish than I think wax is.

    Clear powder coat sounds good.

    If I can I'd like to do an in house job, and I'm not set for powder coat.

    I should setup really, as it comes up for me again and again, and it's only small parts that I get asked for, so a big catering oven would probably be large enough for anything I ever have to do.
