Wow. I was looking at that stuff...I opted against it due to the cheap price $6 bucks. It looks like a great bang for the buck. I have scratch X and UC but definately dont need to use them. I just need a nice lighter polish and if I don't use Zymol HD Cleanse paint cleanee again (just clayed and used the HD Cleanse last week).
I'll give Ultimate polish a basic one pass application and get down to the stressful Waxing project I'm about to undertake (as posted eariler).
