I am going to hang my snowflake lights in the front window and just wanted to make sure there would be no problem with condensation etc, so i am planning on coating them with some electrolube clear protective lacquer. I have already soldered old ribbon cables between the snowflakes to give me a longer distance than the 6 or 7 inches that the supplied flat cables provide. They look great not being in a line and so close together (Pimoroni should really consider selling these with an option for much longer flat cables between the snowflakes)
Should there be any problem with spraying them with lacquer? I’ve used it before for projects that were subject to high humidity. It is clear, can be used at lower temperatures, does not need to be cooked and can be soldered through.
