I found an old fashioned metal oiler is the best tool for penetrating oil
and I usually empty my LiquidWrench spray can in an oiler before using it.
Instead of spraying oil on half the suspension while trying to reach the f'g
bolt that refuse to move, you can put just the two and half drop it
requires, exactly at the joint between the bolt and nut. But you have to
make sure the oiler you use is tight so the volatile components, such as
acetone, does not evaporate.
