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.

I've used Plusgas for about 50 years with good results. Last time was
about 9 months ago.


+1 but as other have said don't always expect instant results. I
recently had a car part that would budge, even when tapping the spanner
with a lump hammer. 3 applications of plusgas over a five day period
and it came off in seconds, without the use of the hammer.

Don't forget that instead of simply trying to slacken a seized nut, it
often helps if you first try to tighten it (especially if the flats have
been rounded by failed attempts to slacken).
