On guardrails on a marine wharf, grating panels consisting of mild steel bars about 1/8-inch by 1-inch on a 2-inch-square grid were painted with a three-coat zinc/epoxy/urethane system. Inspectors are finding numerous pinholes in the finish coat along the inside corners of the grating where the 1-inch-thick bars meet at a 90-degree angle. These pinholes were not noticed in the zinc or epoxy coats, but the final coat's visual inspection is more detailed. What is the likely cause of the pinholing, and what could be done to prevent it on future applications? Also, what should the disposition of the parts with pinholes be, as in, repair, accept as is, reblast and recoat, or an alternative?

On a recent project, complex pre-fabricated, hot-dipped galvanized panels exhibited thicknesses in the range required for the entire subsequent coating system. It was not practical or possible to accurately map the thickness of the galvanizing across all the various parts, and DFT gauges available only measure the entire non-ferrous coating, including the galvanizing. How should thickness-per-coat minimums and maximums be controlled and verified for subsequent coatings?
