Personally, I have never found ease of buffing to be one of NXT's strong points. I found this to be quite a bit of work in my semi-heated garage in the middle of winter! If this is a problem for anybody (and it sort of is for me), similar products are Eagle One Nano Wax, Blackfire, and Turtle Wax Ultra Gloss. With these alternatives, buffing is considerably easier, regardless of the weather.
Thanks,
