The concept is to immerse components in a liquid and seal it. The liquid for starters should be non conducting (electric), good conductor of heat, immiscible with water, should not degrade, hazard free and readily available.
After some research I concluded some sort of oil should be used. Common cooking oils were out of the question because it would decompose on heating and would go rancid with time leaving gooey unwanted stuff growing and leaving residue. Synthetic or mineral oils would start degrading at a higher temperature but then most of them are corrosive or flammable and fume.
Living on the sea shore may be very scenic and picturesque but trust me I know better. All my life I have been living 10 meters from the sea, the only thing separating my house from the sea being a few scattered coconut trees (I must say that it looks amazing). Humidity never drops below 65% and the air is always salty probably because of the strong breeze carrying water droplets from the sea waves. Condensation is very common and this moisture plus slat concoction is an electronics and metal killer
During monsoons humidity increases further, the rough sea’s increase the amount of salt also in the air. Even plants close to the sea start drying because of salt. Every surface becomes a condensation point. Computer SMPS’s keep blowing up, Motherboards get damaged. Any appliance that is not on 100% of the time risks shorting when turned on. Air-conditioning is an option but then works out to be very expensive. Televisions have a perpetual problem I don’t buy any expensive electrical/electronics gadgets or equipments because I know that it is not going to last me more than a couple of years (would be lucky if it lasts for a year).
