Help again! I have a question Refinishing stock..
O.K. I found directions on a website. It is the old fashioned Tung oil hand job. 
On filling the grain, he instructs to mix 2 parts "mineral spirits" to one part tung oil. and sand this mixture until thick with dust, the rub crossways into the grain. O.K. Heres the problem, when I mix it 2:1, after adding the tung oil, it doesn't appear to mix very well as a film of thick gunk settles on the bottom of the can. If you dump out the liquid, whats in the bottom is like honey.Is this normal?, it makes me nervous. I'm using A can that simply says "mineral spirits" bought at the Home Depot. Is there a special kind of spirits I should be using that I'm not?? It says on the spirits can you can use with oil based varnish/paint so I figured it was the right stuff...........help

Ive been refinshing guns for 25yrs and for using mineral spirits i would not mix it with Tung Oil Mineral spirits will raise the grain in the wood,and to rub it in cross grain-all that will do is lay the grain over.Tung oil can be thinned with paint thinner.

Ok, If I may ask, what specific type of paint thinner.....Brand name etc and where do I get it? 0 -
Any brand alchol based thinner. 0 -
Paint thinner is what you should be using. Avoid mineral spirits...

"Paint thinner" can cover a wide range of solvents. A lot of oil base paints are thinned with mineral spirits. Alcohol is generally used with shellac products. Does it say on the tung oil can what thinner to use with the product? Does the grain really need filling or just a buildup of tung oil,sanded between coats, to achieve a smooth finish.On a walnut stock, a beautiful finish can be obtained using boiled linseed oil and rottenstone. Not a lot of talent required, just plenty of elbow grease 0
