De-burred the holes, sanded the edges, and scuffed the R/H wing slat attach brackets, slat attachment support angle, nose rib angle, and tank bay web spacer. Wiped all the parts that are ready for primer with waterborne wax and grease remover, then used a wax and silicone free tack cloth. Primed the parts with SPI epoxy primer. Separated the trailing edge ribs and associated parts.
