Hmmm, makes you wonder if all the hype was genuine? I think you probably need a more aggressive compound as EX 04-06 is pretty light duty. You could try the Sonax Profiline Cutmax or the Menzerna Heavy cut...https://www.cleanyourcar.co.uk/menzerna-heavy-cut-compound-400.
I find using this with a yellow hex logic pad can get even fairly deep scratches out within 2-3 passes. Never tried on orange peel though.
I know the wool pads cut like a bitch, as do the Black Diamond Green pads... https://www.cleanyourcar.co.uk/shinemate-6-black-diamond-green-pad
...need to be pretty careful with those. Recommend a paint depth gauge to keep a track on things.
