@DaveRS3 Yes, I meant to say two stage polish – my mistake.
I’ve machine polished one car previously, and it came up very well, but that was a 15 year old Golf. I’m just not confident enough to do it on what is essentially a brand new RS. If I got it wrong, I’d have to pay to have it fixed. Considering I’m not going on holiday any time soon it’s money I’m happy to spend.
