Yesterday I had a molar pulled so today I do not feel up to working all day on the plane. I did put in an hour sanding the area where I applied the UV Smooth Prime. This is a thick sanding primer designed to fill pin holes and show low and high areas. I worked on some areas with 220 grit sandpaper. I believe this is ready for a coat regular primer. However the UV Smooth Prime directions state to wait 7 days, so this will get done this weekend.
