Chuck has it.
I did a lot of research and a big write-up a while back on my efforts to moisture-proof my Griso's dash. I ran into a lot of material on the web about the Breva too.
Though I wound up with both a ventilation/desiccation system and a conformal coating on my dash's printed circuit board (PCB), I now think a conformal coating is best.
Extracting the PCB from the Breva should be easier than the Griso, I recall. I don't think you need to desolder a ground strap.
Once you expose even one surface of the PCB you might take it to a phone repair place. If they are like the one I use, they will see how large and easy to work on these things are compared to a phone, and might be willing to extract it the rest of the way and then put a conformal coating on it. Or you could just do it yourself. I did, and I had no expertise at all. (My phone shop owner quoted $25 for the job, but he is probably exceptional.)
There is a funny gotcha with these dashes, in that they need to be open to atmospheric pressure because they have a pressure sensor soldered to them that the ECU needs for mixture adjustments. So it doesn't make sense to try to seal them completely.
If you're interested, there's a long thread here covering theory and practice:
http://wildguzzi.com/forum/index.php?topic=84968.0. As mentioned, the Breva dash is a close cousin of the Griso's, with most components being common to them both.
There are as many opinions on this topic as there are on motor oil. My dash is still fine, by the way. It's a great feeling not to worry about it any more.
