Graphite- shutter and aperture blades, NO OIL or GREASE!
Oil- trace on pivots and shafts for gears and levers only.
Grease- spring ends especially where they slide on other surfaces; levers where they slide against other surfaces. A dab about the size of a straight pin head or less is all that is needed. Trace on gear teeth.
The CRC is excellent the other manufacturers stuff may be garbage.
"the ends of the blades are jut stamped indentations that are trapped in their slots in the aperture plate"
Insert an ice pick or similar instrument into the center of the blade end and spread the stampings. The edges of the stamped protrusion can break off, extreme care must be taken.
