I just can't help myself, I guess.  Anyway, here goes.  I have been using silicone, as I said, in my Healey and E-Type for YEARS---and
1.  I drive them both frequently---took the Healey all over Europe for 47 days a few years ago--using silicone fulid.
2.  When I added the silicone years ago, I just flushed out the old DOT 4 and put in the silicone.  So---there was some residue of DOT 4 in the system.  ZERO leaks in at least 12 to 14 years.
3.  You say---"Use silicone in show cars that are driven less hard and 
infrequently."  OK---for exactly what reason?  As I said, my cars are "drivers" and I drive them frequently and pretty hard.  Give me technical data to support this statement.

The only technical data I have seen against silicone use is in racing where the brakes get hot and silicone tends to make the brakes fade fast.  I'm not racing mine, so the benefits of using it far outweigh the reasons not to use it.

Over and out:)
