Great tutorial. I did the same to my electronics. Im using HW xr8 sct pro. Now I can safely run my car in a bad condition track.

Btw, I'm using the CRC Plasticote 70. It comes in a spray can. Using this, you can directly resolder the connection without have to remove the coating. Also you can use uv light to check the quality of the coating whether all surface is properly corvered.
