I am happy to stop at 180 grit. I will still need to do quite a lot by hand though.
Here is a photo in the sunshine (remember that?)
3 types of dips. The little white bits will sand out easily enough. The red circles are dips that I think I will 80 grit nd then use body filler. The long red bit I will leave alone as I will probably make it worse rather than better.
The bits around the head lights will probably also get a bit of filler too
