Boiled Linseed oil can be processed linseed oil. But a commercial BLO finish usually contains solvents and other agents to promote better penetration and faster curing. It was used a lot on furniture and rifle stocks and is still used quite a bit today, although better finishes have been introduced. Starting as early as WWII, BLO was replaced with a Tung Oil formulation. I've never heard of it being used on metal.

Spraying the rusty areas with Duro Extend, a rust neutralizer works well. If you are really cheap, use Coke or other mild acid.

Rustoleum makes a heavy rust primer formula that goes on over surface rust pretty well. Their spray enamal finishes are quite durable and available almost everywhere. Alternatively, auto parts stores and WalMart carry Duplicolor, available in the full range of automoticve colors.

It's all about surface prep. Neutralizing the rust, degreasing before applying primer, a light sanding and another wipedown, and spraying many thin coats outdoors on a warm, still day with low humidity all help.

Rustoleum has some FAQ's on their website, ot to mention Dr. D's Dissertations here.
