I did use newer formula Optimum and DID NOT like it...Main reason is it is separating, and when you mix it back, it looks thick, and never mind...I have used the Optinium protectant and i was satisfied with the results has anyone used the 303 protectant if so is it better than optinium also i would like some hand polish suggestions
303 is very streaking. I hate products that streak.
Get 303 instead, it offers longer protection. Good luck...
Average durability is 4 weeks (per label it's 3-5 weeks)...and that's when I reaply it...I guess I'm too lazy to do it more often...How do you determine that? Appearance?
