If you read every post and understood them all, then you might realize you don't really need to put nail polish in ring cap screws.
These aren't the screws you are looking for.
How about the scope base screws? Getting closer...
The underside of the scope base mates with the top of the rifle receiver. The base screws clamp them together. The friction between the base and the receiver is what stands up to the recoil.
We want to maintain a high coefficient of friction in the crack.
The rifle receiver/ scope base mating surfaces must be protected from oil creeping in the crack.
What SHOULD you put in the crack? Not oil. Not KY, Not Vaseline......... epoxy, loctite, nail polish ok
