Well as you might suspect, I'm a Klasse user and the use of both Klasse "twins" as they're referred to is a good idea. Because KAIO does 3 things it can't do any protection for a long enough time but like someone said earlier, when you apply a coat of Klasse SG over the top of it, your covered and get this, per their recommendations, wait 12 hrs for this acrylic product to harden up and apply the 2nd coat of Klasse SG and your really going to be happy!
Sorry, haven't use the other product so I can't comment on it but rest assured, the Klasse twins really do a great job! BTW, make sure you applicator pad is damp when using both Klasse products, makes life alot easier, trust me. The wetness of the pad helps spread the product out better, thus using less product and less is the key when using Klasse.
Good luck to you!
