I finally ran out of WG sealant and I think I will order its replacement soon since Autogeek is having the Memorial Day sale. Ive been using Klasse AIO and topping it with WG and Ive loved the results, but I see that some here think there are better products out there. I now live in an apartment, so my car is exposed to the elements, so I need to make sure I keep good stuff on it. Should I go back to the AIO/WG mix or do you think that Zaino Z2 PRO + ZFX would be better? The only bad thing I see about Zaino is that the bottles are small and I dont see it lasting as long as a bottle of WG did for me.
