I've heard of owners replacing the standard fasteners with
nice shiny stainless steel screws. Trouble is you can get
dissimilar metal galvanic reactions and then you have to
drill them out.


I am aware of galvanic corrosion, which often corrodes aluminum when it is
in contact with steel, especially if in the presence of moisture and even
more especially moisture with salt. The use of stainless fasteners should
AFAIK greatly reduce corrosion of the fasteners but am unaware of any
change to the galvanic corrosion rates on the aluminum. Are you
suggesting an increase in galvanic action between a stainless fastener and
a plain steel nut? Please expand.

I would also appreciate comment on the use of thread lubricants like
'Nevr-Seize' which IMHO allow increased clamping force and also greatly
reduce thread seizing from corrosion.

All it takes for corrosion to begin is two dissimilar metals and a bit of
dirty moisture (obtainable free from polution and humidity). Even two
pieces aluminum of different alloys can cause corrosion. AC43-13, which
every owner should have a copy of, has an excellent section on corrosion.
