Re: Best penetrating oil?
How scientific is it? Did they tighten them to a certain spec, then let them rust on evenly in a lab?
Very subjective....I have used WD 40 and it works GREAT.
PB is the shizziola. ATF alone works pretty well too, never tried adding acetone.
Time is the main factor....once applied, let the parts sit for a minimum of 1/2 hour.
I have my own home brew called "Poison Oil" which works super.
