Is it possible to use epoxy or polyester surfboard resin for potting

How about the crystal epoxy used for encapsulating insects, etc?
Any other low cost alternatives, aside from flexible rubber/silicone?
Many thanks,

Cheapest alternative: don't pot - it's messy, insecure,
environmentally unfriendly, and makes service and repair just about
impossible.
Unless you intend to make it part of the surfboard, in which case you
should consider a sealed enclosure.

Yes. I have seen candlewax (microcrystalline wax from one of the big
oil companies) used to pot a fm microphone circuit. It seemed pretty
practical to me.

In the olden days potting tar was used, and often still is. Very cheap
but I wouldn't know a distributor anymore. However, it is not very
pretty if that's what you are after.
