Removing generator cover

[Lez72]

Thanks Red. I did wonder if it was the magnetising qualities that were holding it on. The problem is its hard to grip when trying to pull at it  :eek  Once its off is it easy to realign when putting it back on. If I want to get it powder coated is there much to remove from the cover once it's off ? I know this is a lot of questions but if I am going to bugger something up just by making it look a bit tidier then it might not be worth it.
