ust jolt

[z80]

i have this ust jolt thats been in my pockets for a few months and now im going on a trip where i expect to get wet, very wet. i wish to pull it apart and pot compound the whole inside of it. has anyone dissembled one? they arnt expensive but id like not to have to buy another cause i cant put it back together with broken housing. funny thing is i havnt been able to find mention of it at all on this forum and mostly the interwebs are pretty quiet bout that specific light.
