Respraying a Mk1/2 Hardtop

Does anyone know of any good ‘how to’ guides for preparing a hardtop for respray?

I was hoping to get it professionally done but wondering what needs to be removed to get the best outcome and how to do it. I’m guessing the window seal and the trim along the bottom (not sure what it is called?) should be removed to expose all paintable areas? Bottom trim seems really brittle so probably can’t be reused?

Thanks in advance!

The paint guy will advise what he wants removing and probably do it too.

Or consider a wrap.
