Helical grease is not a lubricating grease.. it is dampening grease intended to give resistance... as you can see MicroTools is rated Medium n Light grades.

Vasaline is not a good choice of lubricating medium as it gets watery n runs in heat as well as out gas over time, that in a lens is a bad mix.

Before lifting an element, mark the top surface with a magic marker and use a small suction cup to get it up. Clean the marker off last before it goes back in so you don't make the mistake of flipping it wrong side up.
