Hi, I carry a bunch of tools to maintain my camera rig and other equipment when I go out on fieldwork (very austere most of the time, like no proper rinse tanks you get in the resorts, we have fresh water and use it sparingly to clean electronics like the cameras). These tools are mainly metal and I spray them everyday with WD-40 to prevent rust. But I guess, like it or not things get crazy once in a while I forget or unable to, so by the end of 9 months to a year I find that my tools are have some sort of rust and some are completely rusted.
Does anyone have any tips on how to combat rust? Or is it inevitable?
In my search, I've been able to find a stainless wrench, pliers (actually medical pliers!) but I got other stuff that still rust. For the Allen keys, there are stainless steel versions but not the folding set kind (I tend to lose those individual ones).
