If using this for a car key to get the ignition to work better without sticking; should you apply this directly on the car key or inside the ignition?

The formula within this lubricant was designed to be best used with padlocks, cylinders and mechanisms within the lock.

Is this product good for use with a combination padlock (lock without a key.)

Pamela I don't really know. I've only used it on my key locks and works fine with them. If you put a few drops in the shackle opening it should work ok.

Would this be suitable for micrometers and other delicate measuring instruments?

Yes it should work fine on your micrometers and calipers, especially if they are kept climate controlled.

Silicone based? I didn’t see where it says, only biodegradable?

PTFE formula, whatever that translates to. Good stuff.
