I’m building an ROV with a few friends, and we want to make our own endcaps. I’ve seen other people 3D-print their endcaps and then fill them with epoxy to waterproof everything.

My question is: can I use any off-the-shelf 2-part epoxy, or is there a specific type of epoxy/potting compound that works better for underwater applications and high pressure?

We’re planning to use the ROV at some depth, so I’m mainly concerned about the epoxy cracking, leaking, or failing under pressure.

Any recommendations for specific types or products would be greatly appreciated!
