How waterproof is a Nanni A4 panel

[JumbleDuck]

Some time soon I shall start the installation of my nice new Nanni N2.14. I am planning to put the panel in the cockpit instead of at the top of the companionway step where the Yanmar one rather inconveniently lives. I have just received one of these

from the US to give it some protection and I am wondering whether to cut a couple of holes in the cover for access to the on/stop switch (I chose a switch instead of a key - technically it's the A4 Flybridge panel)

and the start button, or whether I should lift the lid each time. The hinge is good but the push-to-lock/push-to-unlock catch isn't wholly convincing.

Sorry, rambling. Pull yourself together man. Core issue: if these panels are good and waterproof I'll cut the holes and use the cover for physical protection. If the panels prefer to stay as dry as possible I'll open the cover when I need to.

Any views?

PS Please don't use this as a reason to have a go at me for having an unkeyed panel. The choice was carefully considered.

I don't think a couple of holes would cause much of a problem.
I have the Beta "splashproof" keyless panel, it's unprotected low down in the cockpit and hasn't, so far in 4 years, come to much harm although I tend to cover it if leaving the boat for a lengthy period and over winter.
Such corrosion as has occurred is on the connectors, relay terminals etc. at the rear of the panel due to general dampness.
The Nanni item looks at least as good as the Beta as long as there's no chance of water ingress between the buttons and their bezels.
IMO of course!
