Looking for a penetrant to get some seized parts separated.

Does anyone have a favourite (Plusgas, WD40, WHY).
I would prefer aerosol but am not immune to being told it's much
cheaper and really no more difficult to use a liquid.

Interesting question.
I know WD is water displacer recipe 40. According to the 5l container I
have, it is advertised as 'Penetrates, LUBRICATES and leaves protective
film'.
I also use Duck Oil which is far from bad.

you'd have thought somone would come up with snake oil for this
if you want something slimy and slippery ;-)
