resin overhead. If resin is put on the outside then you have to apply paint or gel coat over it since plain resin without tint is not UV resistant. Other than not being a color match the putty is OK without being overcoated. It is handy for emergency repairs and it keeps well even if you just use a small amount of it at a time. But if you do get a rock chip or other small bash in the fiberglass while traveling it makes a great filler that you can apply right away.
I don't have any structural problems that I can see. I was just suggesting that I would never get in a hurry to cover up the ceiling until I was sure there were no possible areas that may leak after the "rat fur" was installed. I do have some areas (quite a few actually) that appear thin and you can tell by the amount of light
that comes thru. I had repaired a couple of leaking (thin spots) last fall
before going to AZ. After seeing a few more drips there I decided that I would cover the entire surface with fiberglass resin. I read where you don't have to use cloth unless there is a structural problem.
I know working overhead is not going to be easy but I think I'll mark off my progress with magic marker as I go along so I know where I left off. Nothing I hate more than to have to do a job over that I did hap haphazardly which I can say I did quite a few times in my life.
I have no idea what I will use to cover the ceiling when I am ready. Some say marine fabric of some sort?
