How many coats of oil finish should I apply?

Most oil finishes need 3-4 coats for a good result. Apply generously, let soak for 20-30 minutes, then wipe off excess. Sand lightly with 400-grit between coats for a silky finish.

What is the difference between Danish oil and tung oil?

Danish oil is a blend of oil and varnish that penetrates and dries harder. Pure tung oil penetrates deeply and cures to a flexible, water-resistant finish but takes longer. Danish oil is easier to apply; tung oil is more natural and food-safe when fully cured.

Is linseed oil good for wood?

Boiled linseed oil (BLO) is a traditional, affordable finish that penetrates well. It dries slowly (24-48 hours per coat). Raw linseed oil can take weeks to dry and is not recommended for furniture. BLO is excellent for tool handles and workshop surfaces.
