Mineral Spirits, Turpentine, or Paint Thinner (to make 1 gallon total) <> Half and half turpentine/linseed oil with 1-2 pints of pine tar/5 gallon mix <> <> paraffin wax - good to use or just use old candles or canning paraffin (cheap) mineral spirits - don't use this - very unhealthy to breathe fumes - use turpentine instead turpentine - good to use pine tar - might be OK but hard or impossible to find - good to add to mix but will make the mix more flammable linseed oil - good to use exterior varnish, i.e. spar varnish, not urethane varnish - good for above ground use only My mix included: Paraffin slowly heat the paraffin in a large container until it melts Linseed oil add the linseed oil to the melted paraffin Turpentine: add turpentine to the wax + oil - diluting the mix with turpentine will help it penetrate the wood - you could always make a mix with turpentine for primary treatment then another without for final treatment <> <> If you're looking for pine tar, try a horse store. It is used to keep their hooves strong, and protect them from chipping. Also try a ship chandler, they may still have it. Horse store will probably be cheaper.
