Help with Garnier Fructis Surf Hair Texture Paste, and Wonder Wave Spray?

Okay, I have heard it makes your hair greasy (the surf hair paste), but that is only when you use to much. And I wanted to know, the differences between using it when your hair is wet, and when it is dry? I was thinking of, after getting out of the shower, spraying my hair with the wonder waves, twisting my hair, and wrapping it into a bun. Then when I wake up, take it down. It would still, most likely, be a bit damp, then put in the paste? As in twirling the little waves that form from the spray, and bun. Do you think this would be a good plan? Please and thank you!
