After sanding the UC with 1000 grit I've noticed a few areas with these pinholes. They appear to go down to the blue base coat and not below. Some are in areas that has filler under it and other places it's just paint over steel. In the photo, the white holes are just holes full of sanding debris. They look larger in the photo than they are. They're actually only around .010" diameter. This is a driver so I'm probably not going to attempt to eliminate the pinholes but I'm just curious as to what caused them.
