If the fastener is providing a critical function, or may be lost, degrease the srew head - after you tighten it, - with alcohol or paint thinners, and then apply a small amount of ladies nail varnish as a sealant, if you need to undo the fastner remove the varnish with a sharp pick, like a dentst might us on a tooth cavity - sisters or mothers are really useful, they normally have red and clear camera sealant in their hand bags.
The varnish wont normally penetrate down the body of the screw, it is too viscous, and it only needs a 'dot' across the screw head edge. Your OM probably has lots of dots hidden below its covers.
A Kiev will rust if you employ it in locations were the relative humidity may be high, and at night at altitude this may be true where you live? My Kiev is a rust bucket, any excess lubricant is a dirty red/black colour. The fungus was more easy to remove...
The nail varnish wont be practical for some of the screws - like for the frame counter gears, (which can become lose,) one can apply a little thread lock to the threads of these screws, this still will allow removal, and will stop vibration unscrewing, and will avoid the rust or galling, but you only need to use this in a very few places and only if you are treating your toy like a professional would. You need to use the screw lock compound rather then bearing lock, the screw lock does not harden much, the bearing lock is similar to epoxy resin (or rust). Dont use locking compound on a camera myself, a car yes, camera no, but then I dont vibrate my Kiev.
I've had a Kiev jam on a free screw...
Dont recommend using 'oil' - I instead employ the PTFE based liquids or greases they won't 'creep' to the same extent as oil which is rather mobile over time. Apply as little as possible of the liquid from a dentists pick, rather then a squirt from a tube. The grease is useful as a third hand at stopping small screws 'jumping' on to the floor, so it serves two purposes.
Suggest surrounding the Kiev with foam padding in a car or bicycle bag, screws may cause damage if they come undone, like the ring inside a J-8M, vibration is not good. I've had a lose lens ring and mobile lens, not very sharp photos.
I've also had the lens ring on the Russian multi finder come undone and the lens hit a wooden floor and heared it bounce twice, it is very difficult to find the 135mm objective lens on a wooden floor even when you know it is there, vibration is bad.
