So I am going to test my homemade sub, but I am scared of leakage. I have already brought the sub underwater, and there was no sign of it, but somehow I still don’t want to risk it.
I read that coating with an acrylic coating spray could make the electronics more water resistant. Is that true and what is your experience with leakage?
Can I use this spray on the Arduino Board, the basic ESC and the IC2 Level converter?
Thank you very much,
and best wishes
