Best practice for bonnet respray

My old Superb was stood front in towards a hedge for about 4 weeks.

Pigeons took liking to it and scratched the bonnet and the paint is now nearly white. I assume due to acid in their urine.

So, I plan to respray using either rattle cans or my spray gun.

Paint is about £38 for half litre, and lacquer is around £15.

Should I remove the bonnet- and is that easy? Or do the job with the bonnet in situ.

My pref would be for removal so I can lay it out I my garage, but any advice we.come.
