Well gave it a go today. I had washed it last week so just gave a quick rinse with the pressure washer then used some megs nzxt + a bit of snow foam in a bucket + some dodo juice clay lube for fun, it worked well! And fast, I had to go back over 1 or 2 bits to get 1 or 2 spots that I missed but it left a glass like finish, it took a similar amount of elbow grease but obviously much bigger surface area your working with so a lot quicker to complete.
To give an idea I started at 2pm and managed to get it finished washed dried + polished and waxed by 6.30! (Including re-cleaning the wheels (as I blasted up the road in the morning
) Bargin for 12.99 in my mind.
