The answer is no.

It depends whether you are talking about swirly type scratches or proper garks. Garks (gouge/mark) are hopeless, but if you have swirls from poor cleaning etc, then there is a product called Plexus that is great. I have used it with excellent results on polycarb and arcrylic windows (racecars). It is a aerosol type, nonabrasive. Apparently it is a “microfiller”, so it doesn’t remove the scratch as such, but fills it. It also has excellent antistatic and antifog qualities. It is not however permanent, the scratches will reappear after a while, and you will need to reapply.

There you go:
