- silicone
sprays are awful to get on anything one cares about, especially where
long-term visual clarity is an issue, are impossible to remove from
plastics, and often cause degradation themselves; I would like to see
people who put them on things they sell mildly tortured; Pam is
vegoilarrgghh).

Quite right!
Silicon is virtually impossable to remove.

Put a drop of the stuff of a GRP mould.... Leave for 10 mins....
Clean it off and repolish the mould.
You will see a blemish where the silicon was on every component from that
mould... for years!
