<VV> silicone brake fluid

[Frank DuVal]

My results may be different than others, but I have only fully drained, 
not flushed, a DOT 3 system before changing over to DOT 5. But I have 
always done the changeover when rebuilding all the wheel cylinders and 
master cylinder, using the DOT 5 as the lube for the hone.  Of course 
here on the east coast we are usually replacing some of the steel lines 
at the same time...

So what chemical would you put in a brake system to be compatible with 
any brake fluid if it does not fully evaporate?
