Years ago I used Homer Forbys 'dung' oil and didn't like it.
Thank you, very useful information. The previous posts address the various pemutations of tung oil. Even in pure form, it will dry in 24 hrs. if applied sparingly and rubbed in. Pure tung oil does dry to a fairly high gloss with multiple coats.
Here is Dig's (highly recommended)formula for oil finish:
Boiled linseed oil – 16 oz
Spirits of turpentine – 2 oz
Carnauba wax – 200 grains
Venice turpentine - 2 teaspoonfuls
Mix together and heat until it simmers. Simmer for ten minutes then allow to cool.
Be careful it does not catch fire -!!!!
Rottenstone, pumice and whiting are available at any good paint or hardware store, usually Synko brand. Most woodworking supply places like Woodcraft carry these and other finishing products.
I might add, I consider these show gun finishes and would never take these guns out in the rain despite what others might say. If the weather is lousy, I have my Merkel 8 beater or an 870. Why play football in cashmere.
