evenflow- That pic of the #16 on the pad can be a good example! If that's how it looks when you've applied the wax to the pad, then yeah, you could've used a bit less. But either way (that much or less), you could scrape off as much as possible, as if you're really trying to get it all off the pad, and *still* have plenty on there.
I'm all in favor of putting enough wax on the pad so that you don't have any "bare areas" of foam, so the pad in the pic didn't look *too awfully* over-waxed *for a starting point*. From that starting point, you just need to take a step seemingly backwards and get all the excess wax off the pad.
Also, note that any wax that gets forced down deep into the pad will probably be wasted; you won't get it back to the surface of the pad until you're cleaning it out.
You mentioned using a razor blade to get it on the pad; I use plastic razor blades for this all the time, and they're also handy for scraping off that excess.
Heh heh, I *bet* you love #16, what with your Toyota looking like that :xyxthumbs
