Airbrushing Future floor polish question

I am relatively new to air brushing and have read many articles on using Future to finish up the paint job prior to washing, etc. One question is when using Future should it be thinned somewhat before using? It seems awfully thick. If so, is water the best dilutant to use to thin it? Thanks for any advice on this subject.

No, it is sprayed straight from the bottle. It is not thick, it is just about right.
