After what seems like forever, I finally got to a point where I thought I wasn’t going to get the roof any better without cutting it off and starting again. With that being a bit too drastic for me, I decided to use filler instead. It was surprising how much better it suddenly looked with just a thin skim of filler on. It wasn’t long after that I remembered how much I hate sanding panels down. I’d bought myself some long flexible sanders which made a world of difference in trying to get the shape right on the curves of the roof. It’s still extremely easy to go too far tho, as I discovered. As you get closer and closer to the right shape the odd high point shows up too so they are getting tapped down gently at the same time. Pretty happy with the progress tho.
