Follow-up to the LED waterproofing test.

In an earlier video I divided a string of LED lights into three sections of six LEDs each and attempted to put 3-in-1 oil into one string, WD40 oil into another and left one untouched. They've been out in the garden for a while now and have been thoroughly ravaged by stormy coastal weather conditions.
The first thing that happened was that the bottom LED in each string went very corroded looking and went out. This may be because they were where all the water drained to, and because they were open-end up. Latterly two other sections went out, although this may be down to the serious wind that meant they spent a lot of time flaying about horizontally. All strings had corrosion in some of the holders, some at the copper end and most at the steel LED lead end. The winner (if it can be called that) was the 3-in1 oil followed by the WD40. However, it didn't work as well as desired so I'd actually say the dripping of oil into the LEDs was not a success.
