M3_POWER, I don't use the PC to apply EX or EX-P just because they are so darned easy to apply by hand, but I know people do apply it by PC claiming they can get a thinner, more even application. I don't doubt that one bit.
For the second application, I would definitely apply by hand. The mechanics of the PC spinning a foam pad would likely abrade (if only slightly) the EX-P.
To apply by hand, grab a quality foam pad (my favorite is the "blue doorknob" by Viking, easy to grip and applies liquids and pastes with ease.
I think 24 hours is possibly an optimum "suggestion". I've applied 2nd and 3rd applications allowing only 12 hours in between and seen no problems. IMO the 3rd application maxes out the ROI of this product, but you can certainly be happy with only 1 or 2 applications. FWIW, on my first application, I will go over the surface twice just to ensure complete coverage.
