BLO isn't boiled nowdays, it is chemically treated to prevent mildew and evaporation. BLO is not water proof! This is why wood stocked military rifles were treated with Tung oil.Which is water proof and the stocks are submerged in it for 30 minutes at 270 degrees F. Tung oil has no shine and BlO does. Barracks discipline had GI's applying BLO as a topical treatment to shine up their M1"s.
You are better off to use something else then BLO.
