future wash versus flow enhancer? heat wave?

[usurpator]

I\'m using the future wash to get washes into the crannies (is that the right word???) and flow enhancer for everything else.
Suddenly I ask myself: they do exactly the sale thing don\'t they????
And with the heat it might be useful to add some retarder to the water?
Your opinions are most most welcome!

I have used both and the only differences I have noticed is that future needs more ventilation and leaves the shiny-acrylic coating behind.

Flow improver seems better for prewashing (if you do that) because it dries with a thinner coat.
