well I tried "Autoglym Super Resin Polish" and very disappointed, it did not even mask any light scratches ...
Next I'm going to try: Meguiar's Ultimate Compound to hand polish, than Super Resin + WAX on

Unfortunately nothing but a dual action or rotary polisher will remove any light scratches or swirl marks , some polishes contain a filer to try and mask the problem but they are rubbish imho.
