Default How to smooth plastic?

I've got some plastic - the kind of plastic a hairdryer, or the main
body of an iron might be made of - and I need to smooth it to something
like its flawless moulded surface before I gouged one of the edges...

What will be a good way to do this? Very fine sandpaper? A very sharp
blade to pare off some sharp bits sticking out? Heated metal to smooth
it down?

Thanks,

Daniele



One can get it flat and smooth with very fine abrasive, but the
surface will be matt not shiny. A year later you'll notice that the
matt bit is dirty but the rest is clean. No practical way round that
I'm afraid.



That means you haven' gone fine enough on teh abrasive.

T-cut is used in the car world to polish out scratches in paint.


I'd carefully slice off the protruding bits and leave it at that.
