saab 9-5,
You should do a quick seach on QD+ (there has already been some discussion on application process that may help).
As Steve mentioned the 3 oz spray bottles (I got it from wal Mart) work nice. I would do a small section at a time (so the product is still spreadable). I use that method as well as spraying it onto a mf. I have recently been experimenting with spraying it onto a slightly damp mf (with s&w) and the spread has been better and the shine:up .
Gadfly, I have not tried the quik wax, but, QD+ is used by me as a QD to enhance the existing wax (in this case s100/ps21 or souveran). It is by no means a regular qd and does more in terms of enhancing/preserving the shine than other products I have used. People, including myself, have used successfully QD+ in between layers of EX and carnauba toppers, which I do not think the quick wax is meant for. In terms of any scientific answer I will leave that to others more knowledgeble. My .02.
