My old 2005 Breva had a misting dash and I read all of Motos sound work on the matter
In the end I went a different way after I discovered that one of the vents in the back was blocked either by flash from the moulding process or by design - I don't know. I do know though, that a second dash I got to cannibalise for the LCD had the same issue
However, once I unblocked the vent the misting problem went away
It might be worth checking for blocked vents (sucking on them individually works) and dealing with them as breaking into the dash is definitely doable, but not for the feint hearted
I might have just been lucky, but the conformal coating certainly wont hurt once you get in
I’ve been lucky so far with my ‘07 Norge.
A small amount of misting on about three occasions, but generally no issues. I did wonder at one point if I could fit a small tube into the cluster and face it forward under the tank, in an area of incoming airflow.
Also a second hole for eflux of incoming air.
I never did get around to it because I hadn’t needed to...(yet).
