I keep waiting for someone to mention this, but Ultimate Fast Finish may in fact easier to use, but I became completely uninterested when I read a post from one of Meguiars product and training specialists saying UFF WOULD stain black trim and rubber.
That makes it the only WOWA sealant that cannot be used on trim. In my opinion, I do not care how easy it is to apply and remove. Part of the appeal of these types of sealants is the convenience to use them on virtually ANY exterior surface and know they will protect and at a level enhance the appearance. If I have to worry about accidentally hitting the a molding with my applicator I may as well find my bottle of Nu Finish and use it. (I'm being a bit facetious, but the truth is I personally do not see the product being much of a success for the reasons I mentioned above)
