> Parts were dipped in paint rather than sprayed leading to fuller and thicker paint coverage

This doesn't sound right to me... You can apply powdercoats much thicker than wet paint because the lack of an evaporating liquid carrier means much less worry about runs and sags. Modern powdercoats can also be much harder than traditional wet paints, and often more chemical resistant. They're also better for the environment, since you're not filling the air with evaporating solvents.
