I was wondering if anyone has used Ultra-Poz. I do have a friend who has it and loves it, but wanted other opinions. I was also wondering if it is similar to Diamond Brite? I definitely don't want PebbleTec or PebbleSheen or anything similar. I just don't like that look. It also seems like Ultra-Poz is more durable than the 3M Quartz, at least that is what I've found through my research. Any opinions?
