In my opinion you should be very cautious about using it on very fine sized bolts in your lens mounts. It can be done but be aware of the pitfalls. Use VERY small amounts of the correct grade. Incorrect tool choice or application can easily cause the screws to shear as well and you are adding to the required force. Invest in some good instrument screw drivers as well. Actually you can entertain yourself for hours browsing and shopping on the specialist sites that sell such tools. Not meant to scare you, very likely you won't have any problems. I've disassembled the M mounts from several Zeiss (Cosina) lenses and they are fitted with thread lock and are removable with care. Dependant on the fasteners' locations you may want to consider locking them externally with a tiny drop of lacquer (like the suggested nail polish) instead. That has the advantages of being more readily removable as well as acting as a teltale for any fastener displacement. Plus if you choose the right colour it can complement the sparkle in your eyes.
