Anyone here has experience with do-it-yourself potting — in the sense of fully encapsulating — of flashlight electronics for improved reliability?
PFlexPro mentions that he uses Stycast 2850FT (https://www.pflexpro.com/Potted-Flashlight-and-P60-Drop-In-s/1841.htm). This stuff seems a bit expensive though, and not available in small quantities.
I also found a previous thread where 18sixfifty mentioned he uses a 50/50 mix of silicon carbide and JB Weld. However eas mentioned JB Weld contains 5-10% powdered iron which might lead to slow shorting of circuits.
