I was wondering what was the best way to polish plastic? I am thinking about getting the KS-auto kit, but this utilises the OEM back of the car with the plastic polished.

i.e. :

I think the kit would look no-where near as good without the OEM plastic being polished, but how would I go about doing this???...

Thanks.

What are you going to polish? Instrument cluster, tail lights, convertible rear window?

The Rear exhaust diffuser etc...

I gave up on this link, and tried this one.
