Used the Sonax for the first time today seems to work well.
Wouldn't say it gave a better shine than the aqua wax I had been using and it was very different putting it on a dry car (after a wash). Had to google that I was doing it right
but it was quite quick and didn't require going over twice like aqua wax to put it on wet and buff off once it dries.
So thanks for the recommendation guys.
