Are you aware of any sealer that I could use that is = really=20 thin in the beginning and that would flow in=20 nicely?

I also found a lot of = wires to the=20 engine monitoring system (picture 200) being extended in the engine=20 compartment. Is this an area of concern? I was thinking of buying new = sensors=20 with longer cables and run them to the computer box in one=20 piece.
