    Not exactly pedal related.... but I'm working on a prototype circuit for another hobby of mine. I'm building a simple PWM dimmer and control circuit for LEDs.

    Now for my question. This will be used in a damp marine environment (but not submerged). I either need to goop the circuit (like I see some pedal builders do), or use a plastic water resistant enclosure. Max I only need 1.5" x 2" x 1" or so... I'm flexible there!

    Can someone input on what material the goop is made of and if it is suitable for keeping moisture and salt spray out? Or maybe suggest a place to buy small non-metal enclosures?

    Most of the time the goop is one of three things, epoxy, silicon, or glue (from a glue gun). My opinion is that you will probably want a marine grade epoxy. Don't use JB Weld though, it contains metal particles and will screw with electricity.

    Place the circuit in a small plastic enclosure and then pour this in the box.

    It's resistant to all sorts of stuff.
