How can I estimate the electrocoat usage of a part?

Electrocoat usage per part is usually determined by multiplying the square foot of a part by the ecoat usage per square foot. The square footage should be supplied by the part manufacturer. The ecoat usage per square foot can be determined by two different methods — average and theoretical.
