Attacked it again with 1000 grit today.
After weeks and the lacquer fully drying, it turns out i didn't flatten the imperfections enough, so the patches in the very first pic reappeared.
So today i took the bonnet off again to do it over again.
I have since learnt that my first time sanding was incorrect by using hand only, so this time I am using a block to help and keeping a good eye on flattening every thing down this time round.
Sanding continues tomorrow
