    it depends on how deep the scratch is,if deep use wet and dry sandpaper wrapped around a block of wood,use soapy water,slowly work down to finer grades as the scratch disappears. then onto abrasive cutting compounds like t-cut or g-3/g-10 etc,use lots of elbow grease.
    the trick is start coarse/medium work down to very fine to remove each applications scratches.

    have a look here for g-3 compound. http://farecla.com/products/1-2-g3-range-compounds

    Any scratches not so deep as to be discernible by dragging a fingernail across them...
    Are easily removed by repeated applications of Simple silly Automobile Wax. Apply..let dry.. Buff..... Repeat several times 'till all scratches are gone.
    Never owned a old Convertible with a plastic rear window?

    Novus scratch remover is perfect. I've taken totally beaten up & trash worthy dust covers & made em look like new.
    It's not that expensive either. I think you can actually get it at places like Walmart.
    And a little goes a long way. Ya just need a bit of elbow grease or polishing pads that pop into a regular drill.
    Hope I was of some help. =)

    Where they are too deep to polish out, I've known of some people having them wrapped.

    (think car window tint, available in shades from clear to dark)

    A specialist should be able to achieve a very acceptable finish.

    Scratches are never too deep to polish out, as long as you have enough material thickness left.
    Dependant on depth of damage, wet and dry used wet, soap can help, grade dependant on depth, but finish with 1200 grit. Then use a medium cutting compound (for paint) and finish with T-Cut. Use rotary movement and not back and forth. I renovated some pretty rough rear light clusters on a Triumph Stag this way that ended up looking like new. Hard plastics like Acrylic and Polycarbonate are pretty easy to recover this way, I've done a lot. Deep scratches in Glass are a lot harder to deal with, once spent 3 months polishing a high value piece by hand, couple of hours a day, but it came good in the end. Patience and elbow grease will get you there. Once made a turned acrylic chess set which polished up nicely.

    Using the cutting compound saves a lot of time getting from the matt finish left by the 1200 grit to a high polish achievable with T-Cut. T-Cut will take a lot of work on it's own on a large area. CarPlan (makers of T-Cut) make rubbing compound, try your local auto factors, its more of a paste and feels grity between the fingers. If the scratches aren't too deep, the cutting compound/T-Cut will be enough.

    T-Cut is just a very very fine grade of cutting compound.

    Good luck with it Brian.
