Ah, brilliant! The point of the kit is to keep it as simple as possible, removing a bottle is exactly the direction I'm trying to go...
That said, having a water bottle, it doesn't sound like adding too much and having something around without a bunch of chemicals in it... But, the water bottle is definitely optional. As is the OPC 3:1 bottle if you've got some protection on your paint (kit is also for exterior use). And then really, the ONR bottle is optional if you don't have any protection on your paint. Could just run around with OPC 3:1 and water...
And, thanks for chiming in Scottwax!
