3M
makes several potting compounds that would be of interest for your
application. There are dozens, so you can pick and choose the
characteristics that are most important to you.

  engine monitoring 4P

  Dear
  subscribers,

  I got tiered of looking at how all
   the wires run through my bulkheads (picture 186). There were even 
some gaps
  and I questioned that this would seal very well.

  Since I was too cheap to buy the
   300$ sealed bulkhead connectors I decided to make my own (picture 
202, 203). I
   made a sleeve out of aluminum counted the wires and drilled a hole 
for each
   wire/cable with the right size. I was planning to fill the back side 
of my
   bushing with approx =C2=BC=E2=80=99=E2=80=99 of flox to make the plug=
 air tight. I was 
planning to
   make the flox really thin that it would flow in nicely and would seal=
 
good
   around my wires. I am concerned now that the flox might not b
e 
flexible enough
   once it is cured. Are you aware of any sealer that I could use that 
is really
  thin in the beginning and that would flow in
  nicely?

  I also found a lot of wires to the
  engine monitoring system (picture 200) being extended in the engine
   compartment. Is this an area of concern? I was thinking of buying new=
 
sensors
  with longer cables and run them to the computer box in one
  piece.

  What is proper for heat protection
   for the cables in the engine compartment. I found products that last 
to 500
   degrees F. Some silicone/fiberglass combinations run up to 700 
degrees. Can I
  go with the 500 degree products?

  I do not have any documentation on
   my engine monitoring system and I don=E2=80=99t find anything on the 
internet. Can
   anyone give me a file/ copies for the wires installation sketches and=
 
set up
  instructions?

  I got also done with my brakes now
  (picture 195). I used aluminum hard pipe since it is a very similar
   application which is used in our Cessna. I also used plasma nitride 
for rust
  protection on the rotors and drilled them to get more
  surface.
