This may sound like a real stupid question but how much solid wax should you apply to the buffer pad?
Very little. Use just enough to evenly prime the pad *shallowly*, do not rub it deeply into the pores of the pad.
Then try to scrape as much back out/off of the pad as you can (I use a plastic razor blade for this).
Most people use a zillion times more wax than necessary and they're just wasting effort and product (all the wax you buff off the car, and all the wax you clean out of the pad, are completely wasted; the only wax that really counts is the infinitesimally small amount that actually bonds to the paint).
If there's a significant amount of wax left in the pad when you're finished you used too much.
The last time I used up a can of #16 there was a tiny amount of wax in the recessed rim at the bottom of the tin. That little amount was enough to do the entire A8 via Cyclo, and that's not a small car
Im pretty sure I read with liquid you should use a quarter size but wasn't sure how to judge if you are using a solid...
That "quarter size" amount is *WAY* more than I'd ever apply to any size waxing pad. Use less and reload the pad as needed.
Often when you think the pad is out of wax, if you swipe it across a piece of chrome/glass/glossy black plastic you'll see that it still has plenty of wax after all.
Remember that "is there wax left in the pad at the end?" test.
