more roof sanding

I put some primer on the roof but then it rained and even though it was covered the paint did not cure correctly in the high humidity and heat. Also....I noticed all the little defects where my sanding job fell short.....I resanded and will attempt to prime again. I really don't want to sand much any more......the body filler that I used to skim coat is killing me. I have never worked with body filler or any other resin for that matter so the learning experience has been brutal. All I can do at this point is to keep sanding.

So It may look like my posts are out of order but they are not. This is what it looks like now.
