Doing a search, I see people have suggested using potting compound, silicon, 2-part epoxy, and maybe hot glue for weather proofing outdoor arduino installations. What’s a cheap option?
The epoxy’s at the hardware store are kind of expensive.
Can I use a $3 silicone caulk? Is that what people mean by “silicon”?
Would hot glue damage the circuit because of the heat when applying it?

Right, I forgot to mention the conditions. This will be in Wisconsin - cold, subzero winter conditions, fairly hot summers, morning condensation. It’s going under the eves, protected from rain for the most part.
