Getting ready to install a Penguin AC unit in the front bedroom of our camper. Got the roof vent removed and after three days of working at it I finally got all the lap sealant and butyl tape off the roof membrane. My question is, what do I do about the screw holes in the roof? Will the AC gasket seal them of should I put sealant on them and let it dry before installing the AC unit?
