What is the best way to maintain our flashlights.Like my p3d rebel.I was wondering what is the best thing to use to lubricate the o rings and anything else that would be beneficial to keep them in top shape.
I use the red cleaner/lube on threads that need to conduct. I also picked up DeoxIT pen somwhere and I use this to clean the other contain points (springs, etc).
You can also use Nyogel on the o-rings and threads:
