Fellas, i remembered this little thing in my sleep:
Since you all complain when cleaning the container about it's sharp edges, why not put a piece of a rubber hose cut along it's lenght on the opening? at least it would prevent cursing and cuttings a bit more...
(ahh, good old Paint![:)])
Oh dear I should have taken note of this when changing my fluid! Its not just Citroen "Green blood" in there anymore! Silly thing is I read this first and thought id be OK!
