I should do this.. Agreed on the factory sound deadening, I spent a whole day with some dry ice removing it from a track car. Never again. haha
How many square feet did you use for the whole cruiser?
Keeping in mind that I did full coverage + double layer in the center of the big panels (*all the panels*)... I would grab 4 packs (144 sq ft) of the deadener and that should be plenty to get you through the entire floor, all 4 doors, the rear panels, the tail gate, the wheel wells, and any other flat areas you decide to stick some.
For the foam, I think 100 sqft would be more than enough.... I used about 40 for the doors and sides
This is what I would order:
