Guess I'm being nit-picky today, but this page
http://brakefluidtest.com/news/specialreports/map-standards-and-guideli.shtml
refers to Dot 5.1 as "silicone.'' I don't believe Dot 5.1 BF is silicone
(as discussed on a recent thread on this list).
It bugs me when when someone trying to sound authoritative gets the
facts wrong. Pretty much throws the whole premise in doubt (it's not a
simple typo).
Otherwise, this could be a useful product.
