New member, Andrew G, has pointed me to this great and useful DF95 video about waterproofing your onboard receiver and other onboard electronics using “Corrosion X”

One of the notable things to me is that they are using a pointed 1oz dropper bottle to dispense the fluid. It looks like in North America 1oz dropper bottles of Corrosion X are easily available. At the time of writing, in UK I haven’t found this product packaging. The same company are doing a fishing reel lube called SpeedX in a 1oz dropper bottle, but that seems to be it.

I’d rather have some small amount of Corrosion X in the boat tool box and with me all the time. I find through past experience that if the cap comes off those dropper bottles it will leak everywhere. Instead, I am going to try one of these (very cheap on Amazon)

It has quite a pointy end on the pipette which I thought might be better for this particular job, than the ones with olive oil to stick in your ear! And once that lid is screwed in, I reckon you are going to be safe against leaks in transit. The bottle size I chose is 50ml… so about 3 tablespoons – that should easily be enough for radio sailing.
