Carnauba wax gives a harder finish than beeswax (most traditionalists still use beeswax)Venetian turpentine also helps the finish to be harder but also gives the oil 'body' and the finish a certain 'depth'.
Tung oil can give some people a rash so take care.
Most 'Antique' oils are Tung oil with driers and may have spar varnish or polyurethane added, that may be why they are harder,shinier and faster drying than Linseed.
To each his, or her, own.
I am proud of what I produce and happy.
Last week a very happy customer showed off his gun I had just refinished for him, to a friend.
Saying the following "look at the finish, wood that beautiful doesn't grow on trees" ???????????????
