I like Yo's response. Since the AIO needs a wet aplicator, I like the damp microfibre pad over the foam pad. It is small enough to not soak up too much AIO and waste it.
For the Sealant Glaze, I will probably use a dry MF or a foam pad. I used foam last time cause I didn't have an MF pad.
For the Wax (Blitz and Souveran) I will use the....I don't know yet - either foam or MF.
In other words, a good foam pad or a good clean MF or cotton pad will do the job. Many used foam cause the cotton pads soaked up too much liquid and you couldn't put it on thin enough.:xyxthumbs
