On the deep scratches it may not completely take them out, but it will minimize it a great deal.
If anyone has something to add to this, please do so!

This principle is also exactly why you don't wax your paint on a hot day. This same principle puts scratches in.
That's an interesting concept for plastic though. One thing I would question is how it affects the long term strength of the plastic and resistance to later heat and UV damage.
It could be a *great* idea, or it could be shortening the life of the plastic.
One way you can get out scratches on hard plastic (like your wind deflector or headlight lenses) is to just use polish and finish with a fine polish that leaves it glass smooth. That's how you polish metal too (natural finished).
