WD-40 does not set "hard". However, it redistributes all the hardened grease into a thin layer throughout the sprayed area that, indeed *DOES* set hard once the volatiles dissipate. Unless thoroughly rinsed away.

WD-40 is wonderful stuff if properly used and well understood.

Too damned bad that, although some here appear to have this in hand, such basic knowledge seems to be scarce in one small corner, under one small rock deep in the Antipodes.
