    I like others would like confirmation that this [Abbey] SM50 does exactly what it says on the 30ml dispenser bottle.
    . Is there anything - including non-airgun - that it's safe to use that stuff on?

    quote from the latest daystate owners manual on cd rom -


    Daystate recommend that a synthetic based oil is applied to a cloth be used to wipe over the entire outside of the gun, making sure that the entire area is covered with an even amount to protect the metal parts. Do not use oils that contain rust inhibitors such as 3-in one oil, etc.

    Sorry Tony

    Does this mean that silicone is a synthetic oil and can be used on my Mk3, because I've assumed that that's what it is and I've wiped it all over

    Wish I'd used 3 in 1 now!

    I think they (Daystate and Theoben) used to recommend these products.

    They are Synthetic NOT Silicone.

    The acetone should shift it. Might be worth trying in on a test bit of metal first, acetone can also bugger plastic and rubber, so be careful.

    Gatito: If you have only been using to protect a surface (rather than as a lubricant) I wouldn't bother. From what Ben has said this stuff kills quickly so if it was anywhere where it could do its nasty deed it will have done it already. I'd just wipe it over with a clean cloth and then wipe over some nice safe gun oil

    Yes, nasty stuff if you get it on plastics and rubber but I'd rather strip the bluing than have silicone migrating from the externals to the internals!

    Silicon oil actually soaks into the metal, and as Ben has rightly said the only way to remove it, is to remove the contaminated metal by grinding it off. You cannot remove it with any solvent I've ever seen, and I've used solvents that would stop you breathing if you got a whiff of them.

    If you find that hard to believe, how about this, metal has also got a grain pattern.

    Silicon oil has it's uses, but should only ever be used in very tiny amounts, it is ok to use one tiny drop on a sythentic piston seal in a springer, as mineral oil would diesel and possibly soften the piston seal material, also another accepted fact is silicon oil won't ignite and cause dieseling, wrong, if you use much more than a small drop it goes bang like any other oil.

    There always semes to be a tendency to overdo the lubrication on airguns, less is more as our american cousins love to say.

    Gatito don't panic, I have found some gun finishes can be damaged by mineral oil, but silicone oil is ok for most finishes, just a hint of it on a cloth will do the job.

    Thanks Gents

    Just found this http://www.struers-solutions.com/res...006-01-06).pdf it's an MSDS for silicone oil - seems to be dissolved in paraffin - any chemists around? Is paraffin the solvent for those who've got problems with the iinternals? Paraffin bath? Leave stuff in for a couple of days? For anyone who's got something that's already b*ggered, perhaps there's nothing to lose by trying it out?

    Luckily, I've only given mine a single very sparing wipedown but I'll be giving it a wipe over with paraffin (and acetone) tonight just in case.

    i tried a silicon destruction test on the lathe today and it is frightening how quick it starts grabbing and chewing metal


    i have had a bottle for a couple of years and am now really worried about what its got into.

    i also hope it doesn't cause dermatitis as i have also found another use

    I tried test in lathe with Comma silicon spray, it did not grab or siese, this was with high tensile chrome-moby steel as was all I had to hand at time.

    We use u-pol system 20, it is toted as anti-silicon, remembered now that friend used acetone to remove also. There should be other degreasers that remove it as it is a problem in car respraying

    You live and learn. I knew steel could absorb carbon to toughen it and hydrogen to embrittle it, but never heard of it absorbing a liquid before, well, not beyond the surface cracks. Rust pits would soon gob it out so that ain't it.

    Brake disks are a bit different being cast iron with a spot of magnesium. I can see how they might absorb a bit into the slag inclusion
