Good thing you went on the roof. I need to get a roll of that stuff for emergency.
Hard to tell what your talking about on the bunk area. Is it the curved line on the front? Is that a large crack? OMG. I guess tape it for now. But its in a highly visable area so not sure If I would use white tape. Perhaps some clear epoxy and a small model brush or tooth pick to apply?
Do some searching on the old Inter-web and see what others have used. I would look at Youtube as well.
Let use know how it turns out.
