Wet sanding

[Grant]

As above Tom, your ate getting wax and polish mixed up. Polish will 'wear down' the paint. The courser options being g3, tcut etc, working the way down the scale to things such as me guitars scratch remover or autoglym paintwork renovator etc.

You should apply a cut, finer cut (depends how mad you want to go but another finer cut), polish and wax(s)

To be fair, from the pictures it looks like you have done a decent job. Must have been hard removing the scratches from 800 grit paper! Lol. Nice job!
