Today, I finished drilling the the cabin roof to the root ribs, and then the front carry through. I then began to remove the entire assembly to deburr and prep for priming. I removed the plastic from the top of the cabin roof skin, then deburred, cleaned and prep'd. I also removed the R-Bulk assemblies, cleaned and prep'd. I primed the two over the main cabin area. I also reworked a couple of the clips that secure the root ribs to the front carrythrough brackets.
