I don't know what staking is, and I think they are trying to avoid
masking/demasking.
The goal is to spray everything except the mounting holes and a few exposed
metal areas that we are using for thermal reasons.
I was told I need to leave an "overspray zone" as neutral territory between
those two types of areas
