From the aircraft world, check out ACF-50

I have also used Corrosion X, its ok.
As well as Bosehield

Didn't like the spray can.
Boiled linseed oil in sealed tubes has been the standard for years.
After 35 years in the aviation industry, I keep coming back to ACF-50.
ACF has the advantage of smelling decent, unlike the others. Do not use prior to paint, the stuff creeps uphill and will mess up paint prep. I would tell my customers to not use for a year prior to major paint. 35 years in the SFO Bay Area means corrosion has been a lifelong battle.

^ Thanks I'll check out this stuff. It works on steel too right?
