Still the same, less is more philosophy, for both products. UNO can still do 3 in 1 duty. It also comes off easy. However, using non rotary polishers, on flat black paint you need a less aggressive product to eliminate the very tiny "pigtail" marks. Use UNO on a metallic black paint and UNO is the only product you will need.
Having said that, the new HD POLISH is an amazing product. I spent 5 days on a black Mustang and it was the best looking finish I have ever produced. Thanks to UNO, and POLISH.
