That restoreFX is just a product full of fillers to mask the swirls. It will wash off just as Autoglym Super Resin Polish does. That's OK as long as you are happy to re-apply it every so often but if you want that deep lustrous shine you have to correct the paint properly.

Machine polishing is not difficult, but it is rewarding when you see the results. Well worth doing it right, and especially so on the dark colours where it comes up better than new.
