|
|
I read in an old army engineers manual that linseed oil could be used as a preservative on metal. I like experimenting and painted a new chromed spanner with some which I then left outside for a few months.Afterwards the spanner had a dull coting which when removed with turps revealed still perfect chrome underneath.
The book also suggested dropping hot steel components into a bath of linseed to leave a black protective finish on them.
Asking around I found some other people had heard of this and some had used it with success,has anyone on here used it? _________________ Thirty years selling imperial hand tools for old machinery(Now happily retired). |

Any Ph neutral substance with "cling" will protect a metal surface to some extent. Most natural oils have "cling" - that's why they're sticky.

I'm sure I read somewhere that the wrought iron suspension chains of Telford's Menai Bridge were preserved by being dipped in hot linseed oil - presumably in component form! Certainly boiled linseed oil can build up a nice weatherproof coating on exterior woodwork as it oxidises so it will do some good, but I think I'll stick to proper cavity and underbody waxes on my vehicles for now. |

Linseed oil also brings back black bumpers which have faded to grey, just don't bundle up the rags used as they can cause spontaneous combustion...... |

Stationary engine guys use is a lot and looking at one of their forums this was what one person said: "You require boiled linseed, not just linseed oil. It can be bought from places like Wilko. Mix it 50/50 with white spirit. Apply with a brush, but brush it out very thin because it will run and pool at the bottom. It takes several days to start to dry, and weeks to be fit to handle - so don't be in a hurry!" |

In the same book they talk of dipping iron components in linseed when they have been heated saying that it leaves a black coating that resists corrosion. _________________ Thirty years selling imperial hand tools for old machinery(Now happily retired). |
