Thickness of zinc, method of application, more paint applied, etc.

I worked in a structural steel fabricating mill. Paint was applied using an airless apparatus with a hand gun much the railroads used. A a manual process the gun often dripped whenever the painted stopped.  While fairly uniform, there were areas in higher mill thickness. Paint specs only called for minimum mill thickness and color.

As to the screws I removed,  their heads varied from a few that looked like they were fresh out of the box, the rest had varying areas of rust, mostly 75% to fully rusted.
