Applying plastic coating to Raspberry Pi for water resistance

Making sure that water condensation will not damage this Raspberry Pi when exposed to high humidity conditions. After covering few ports I've applied protective layer of plastic coating so most of the electrical components are isolated from external factors. This almost makes this device #water #resistant.
Connected cables to 3,5mm jack, HDMI and microUSB ports. Also masked GPIO, USB and RJ45, CPU breathing hole, and microSD card terminals. Left unused pins and connections unmasked so plastic can penetrate it and protect it from water and moisture which can cause short circuits and damage the board.
USB pins are not that close to each other so I'm leaving them out.
Used heat gun to make the #RPi dry faster.
I'm using plastic in a can bought in local electronic shop.
I had some experience with RPis running in closed cases placed outside and moisture getting into it can cover GPIO pins and damaging the SoC. Sometimes it kills the board, sometimes it just kills half of the GPIOs by creating internat short circuit in the processor which also leads to high CPU temperatures and underclocking.

Really smart to cover the CPU / GPU first so that you don't spray that stuff on the surface and trap heat. That's thinking ahead and something I'd accidentally do. Great video! Thank you for sharing!
