Hi,

Can't speak to that product, but Meguiar's has a new (to me, at least)
product called "Plastx." Just did a pair of plastic headlamp lenses on a
Camry that were so yellowed and oxidized you really couldn't even see
the road (and they ask why I like the glass lenses on my Subie!) I was
quite pleased when I finished.

i have used plastx by meguiars as well.  however, nothing beats a good
wet sand with 1500 grit and a clear coat.
