So my bottle of Speed has been sitting for over 2 years as I used it once or twice back then and was unimpressed and chalked it down as a hype product. Used it back then on a DAS6/PC24 with green BnS pads. Fast forward to recently and reached for it again and decided to use it on a 2015 Mercedes and test against Menz 3 in 1 and Megs D166 this time using the Rupes 21 MKII and Megs DFC5 Maroon foam pads. It blew the other two AIO’s away in gloss and correction and boy did it impress me in everything, work time, cut, finish, wipe off, no dusting etc. No idea if the paint this time round preferred Speed or Speed preferred being used with a more aggressive machine and pad. Regardless... I am now a believer.
