My doomed 408 build

WD-40 is not a lubricant! It is a cleaner and will dry up.

Uuumm, huh?

From the WD40 website:
WD-40's lubricating ingredients are widely dispersed and hold firmly to all moving parts.


And:

WD-40® protects metal surfaces with corrosion-resistant ingredients to shield against moisture and other corrosive elements.
