Q30 protective spray

Can we use Q30 protective spray to coat the board for an outdoor installation inside a weatherproof box in a warm, humid, tropical location ( near Durban, South Africa )?

From their site:

Q30 has an extremely high electrical tolerance (up to 1000V) and can be sprayed onto electrical circuit boards. Q30 can be peeled off, and can stretch by up to 1000%. Q30 is 500 hour salt spray test certified and withstands temperatures of 100˚C for extended periods of time. Q30 prevents tarnishing, seals electrical circuit boards, prevents corrosion, seals small leaks in skylights and insulates and protects PCBs.

I'd spray the seals of the weatherproof box, perhaps, but not the Pi/HiFiBerry unit itself.

Even then, consider how doing so might shorten the life of the equipment - it won't be able to breathe.

Why not just throw a few silica gel packets into the enclosure if you want to prevent moisture build-up/damage? or increase airflow through it so humidity doesn't have much chance to "settle" or "stick"... maybe both?

annual/seasonal/monthly (? - might be a bit much) inspection and maintenance of the unit in the box will tell you how effective your solution is.
