Unfortunately, foam has become, IMO, waaaaay too popular for doing actual correction. Wool is *much* safer. You are far, far FAR less apt to heat a plastic panel up to failure temperatures when using wool for any given amount of correction than a foam pad.
PFW is soooooooooooooooooooooooooooooooooooooooooooooooo much safer than foam for correcting *any* surface, not just plastic. (no, my "o" key didn't get stuck. It really is that much safer.)
It's faster, finishes down better (most of the time), is easier to use, develops less heat, and did I mention it's safer?
Why guys even *bother* with foam pads for correction makes me go :nixweiss
