Applying NEVERWET to the EL Umbrella

I have been recently testing the hydrophobic spray called "NEVERWET" to various materials to gauge it's effectiveness and practicality for projects.

Over the course of the last few weeks I have tested it on several materials, but this post is about applying it to electronics to protect them from water damage.

A few months ago, I created a small side project, which was an EL Umbrella --- a clear umbrella wired with cut, segmented EL wire and powered by a lipo, and controlled by a SparkFun EL Escudo board, and an inverter for interactive light show.

On Friday, I had some time to step away from the keyboard and apply some NEVERWET to the EL Umbrella. I had already been sticking the electronics inside a plastic pouch to keep it dry, but thought I might add some extra protection, in case I had to upload some new code to the EL board, and didn't feel like wiping it dry.


I applied several coats of NEVERWET to the board, inverter, and lipo, and all the wiring. I did not spray the EL wire itself, because it is already encased in plastic and hot glue. Also, the wiring for the EL was already pretty well insulated with the hot glue I used to seal the solder joints between EL segment.


I hope to test the EL umbrella sometime this week when it's raining and dark out.

Stay tuned for further NEVERWET tests in the future.

P.S. I should mention that I applying this stuff in a VERY WELL VENTILATED PAINT ROOM specifically designed to suck fumes out. I am also using a full respirator mask, googles, gloves, and long sleeves when applying both top coat and secondary coat. I would suggest you do the same, given the warnings on the spray cans and what I found online, and heard from folks who deal with chemicals on a more frequent basis. Read the instructions and warnings on the can before you begin using this product.
