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
