I would have to disagree. D151 has a bit more cut than xmt360 (slightly less than ultimate polish with similar gloss), especially on a microfiber pad or even a white polishing pad. D151 is giving me 1 1/2- 2 months on the dd's that sits outside 24/7 with the 360 usually stretching to about 3 months. The XMT360 gives a higher gloss but offers less cut, partly due to the shorter working time. They both have their place but D151 is slowly becoming my go to,especially for harder paint on the dd's I work on on a regular basis (2 black tahoes and 1 black suburban, all sit outside 24/7)
