Do you know anything which is good for getting scratches out of plastic. I have an unreplacable DVD which I have a scratch on. I normally use toothpaste on CDs. But this leaves a 'matt' mark over the spot which is millions if tiny scratches.... But thats OK because I can then read the whole CD in and write it on a CDR But for DVD its different and I can't. I want to polish the scractch out to make it 'like new'.. The scratch is not deep (infact its more of a smudge than a scratch).. Is there a product which can polish out plastic!
