Clay mitts are nowhere near as good as a traditional clay bar in my opinion
They also reduce the visual indicator of how filthy a panel really is and to be honest most people dont tend to do it properly because of this missing quite a few places than they would with a clay bar.
It turned out nicely, especially on such a hot day (at least where I am). I've never tried a clay mitt before, only various clay bars.
However I use an Iron remover (Korosol or IronX), a degreaser (Surfex HD or Screwix own) and tar remover before going anywhere near the paint with a clay bar. Doing this first it's surprising how little imbedded dirt is left on the car and how clean the clay stays as I work round the car (even on cars that feel gritty/rough to the touch). It leaves less marring to the paintwork too, so I can often get away with a single stage polish and only two stages on particular marks.
I plan to do this at maybe six month intervals on mine (low mileage car and usually a touchless wash or 2 bucket wash if it really needs it). As mine is a light colour I hope to avoid having to polish it each time too as the chemicals do the hard work and leave much less for the clay bar to do. I'm currently investigating bulk options for Iron remover as it's not cheap, especially in 1 litre or less bottles, but I've found it very effective.
I love the colour of your car two BTW; same as Rayaan's car I think.
I've been intrigued by clay mitts for a while but never actually got round to using one. They certainly sound more efficient than a clay bar as I found them such a hassle.
That said, Ed at Divine Detail gave me a tip with claying which was to ditch the clay lube or quick detailer and go for a bucket of soapy water. Use a wash mitt to constantly wet the panel as you clay it. Made the whole process so much quicker. Although I've not clayed in a while as not gone full on with a machine polish on the CL yet.
