I actually despite ANY opinion or bashing think Griot's Paint cleaning clay is one of the best clays of all time. call me crazy but try it b4 you do. You will be AMAZED at just how soft and malliable it is compared to even sonus green and swissvax even. It is easily said the mildest and softest clay, and they give you 400g instead of the usual 150-200 and it doesn't marr the surface at all. Swissvax paint rubber is a close second, but to me marrs slightly....adams clay is great for rough cars but it marrs like a mothers bar would....typical at the end of the day w/e anyones opinion educated or not, I always reach for my griots clay b/c at 20 bucks I get tons but more importantly its the safest clay and is extremely effective for how mild it is. so i'd say griots for wash n waxes (no correction), adams if correcting and vehicle is sandpaper like, swissvax if your doing like Menz 85rd, and the surface is a little bumpy. what u guys say?
