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?
