ECU corrosion

Greetings everyone!
After going through 3 ECUs on my 2 Stelvios (2012 & 2013NTX - each about 30k miles, first burnout at 15k) I undid the four small screws between the heat dissipator and the electronic board. The attached pix show enormous corrosion, which restricts the heat dissipation and possibly hinders electrical conductivity (by way of the grouding screw affixed to the heat dissipator).
Has anyone come across this or have a suggested remedy? Not wanting to risk the effects of inserting a conductive and moisture resistant grease, I cut out a soda bottle and made a semi-cylindrical faring around the bottom of the ECU on the bike, to reduce exposure to rain, snow, etc...

Nice idea they had if it works but it doesn't keep everything out. You could dip it in the stuff that you put on pliers handles, leave the fins. Don't know if that would work but just an idea.
 
I specifically put up the pix of the corrosion because I found the same on two of my 4 ECUs. Those two Stelvios I had bought used and they had no ECU protection; the new one ('17) and that on which I swapped the ECU ('12) are now protected. I also have used various waterproof and conducting greases on ocean research buoys.
However, my question was why is this junction not protected right out of the factory by Moto Guzzi (or whoever they sub out the ECUs to)? The effects can be life threatening, (failure while on left lane on highway!) which seems to warrant a major recall...or is it just my bad luck???
