I use the same instructions for foam pads that I did for the Z cotton applicators: Run the applicator under water and get it soaked, then squeeze, squeeze, squeeze until the pad is just barely damp. Begin applying Zaino; try to use as little product as possibe - thinner is better. About every other panel, spritz the applicator with a small shot of Z6 to keep it damp and to help it glide on the surface easily.
Note: the first couple of panels will require a touch more Zaino on the applicator to get good coverage. Once the pad is "loaded" with Z, it only takes a few drops scrubbed over the surface of the applicator for each subsequent panel.
I typically get 2-3 coats per ounce when I apply by hand with foam . . .
Good luck,
