G'day folks,

I've done a search and yes, I know that this issue is virtually inescapable, but someone always seems to have an idea I've not heard of before.

What are our best/latest options and practices for TRYING to protect electronics from salt spray?

A recent renovation I've done has all electronics located in a bulkhead however I just KNOW that spray is going to get in there eventually.

My thoughts are:

- 3D printing some kind of filters/traps for the cooling fan inlets on equipment.
- Trying some conformative coatings on PCBs/electronics, although this will mean opening them and possibly voiding warranties.

I'd welcome any advice or suggestions.

Thanks in advance,

Robbie.

What electronics, specifically? If you want only audio, some marine stereo units have what's called a 'conformal coating' that covers most of the contacts & connections but I would want to see which amplifiers are fully protected. Fusion head units are rated IP66, aside from the rear- if the enclosure is closed to the outside world, these should work well- they're one of the most-used brands for marine head units and can be controlled via the app. Hardwired is still best, but they do work with WiFi or Bluetooth (they recommend WiFi or wired). Speakers should have the terminals coated with silicone but that still leaves the leads, which aren't always coated.

Good luck with TVs and anything else.
