[TR] information on various penetrating oils

[Carl TR]

Should we assume that the length of time 'percolating was the same for all?

I have an old rusty TR3 cowl sitting next to the garage with the steering 
column support still attached.  'scientifically rusted' by 10+ years of 
Florida humidity.  I have all except the Kano Kroil and I believe 4 
bolt/nuts.   I'll let you know how the un-scientific test goes....

I have used Liquid Wrench for most of my stubborn parts as I did find it 
'better' than WD.   The biggest issue there is the dribble application vs 
spray so have used PB Blaster instead.  I haven't looked lately if LW comes 
in aerosol.

Thanks for sharing...
