'06 VF4
2 places I have found.
One is that the slide-up flexan sidecovers should be made 1 or 2 inches longer. As coolant splashes on and dispurses, it tends to go up and over the slide and thereby dripping all ove the outside.
The other is in the corners. Whenever I fill up or wash with the sprayer, there seem to be a nice puddle of coolant under both corners.
I have not found the exact source yet, but once I do it will receive the plumbers putty treatment.
The MiniLathe, MiniMill and the '01 SL10 seems to be airtight.
