It hardly even does that just like thompsons water seal. Boiled linseed oil causes mold. Mold means water is getting to the wood and this causes rot or high maintenance of wood.Boiled linseed oil preserves wood tool handles and trailer boards.
I don’t think use on metal will work.
I've always use Vaseline.I've found a little mentioned use for Fluid Film... Makes an excellent corrosion preventer for battery terminal connections and ground lug connections on equipment and much less expensive than the commercial red battery terminal corrosion preventer sold in AP stores.
I grew up in a family that use vaseline as skin softener and hand cream.Vaseline requires you to manually spread it with your fingers so it's messy. Fluid Film on the other hand you can spray on so no gooey fingers and the included straw allows you to pinpoint the spray as well and it comes in black as well and batteries are mostly black too. Blends right in. I use it on the underside of my mower decks for winter storage as well (after cleaning the stuck on 'cud' off. That cud turns acidic and rots the deck eventually, especially those thin stamped ones like come on cheaper mowers... and Arly's EGO electric mower as well...lol
