    WD40 is a water displacer first and foremost (I've always assumed that's what WD stands for - anyone know if this is right?). Better than nothing but it all evaporates away leaving little protection. It's also a great solvent, so good for cleaning stuff with, but can dissolve out other grease/oil that would be better off left on the chain or in bearings etc. Not ideal for bikes if it's the only thing you use, but certainly has it's uses.

    I don't personally find GT85 that much better for bikes if used by itself for the chain/cassette, but do use it to squirt into cable inners where it's tricky to get light oil in (which I use for preference everywhere I can easily apply it).

  6. So that's why Ginsters pasties slip down so easily.

    Is SAS20 of the WD40 or GT85 mould?
     
  8. More like WD40, the residue left behind is sticky.
