Thanks. I have used that before and yes it is a pain when you get it where you don't want it (and keep your minds out of the gutter). I like the car window sealer idea. Bitumastic is easy to remove with a bit of alcohol. I just hope it is good enough to stay sealed. This ABS box with be on a motor bike handle bar or head stem.
There will be wires coming out. Some to power and others to sensors. the back half will be filled with epoxy so that part of it will be fine. I am just worried about the OLED display.
