Hi, Ive been reading and reading about removing scratches from PMC and have followed everything above from start to finish as advised atc, yet i STILL have scratches on my finished piece. I have tried finishing with both the 3M papers and the Spectrum papers on 2 different pieces to see if its one or the other, but scratches are still there. Ive bought the silicone polishing tips, and used them in all grades, and they seem to mark my silver. Whatever I do i simply cant win!! Maybe Ive got my dremel on too fast? I've used every kind of tip from fat to thin, and worked through the grades.
Can anyone please please help? Its had me in tears again today!!

I have tried to make sure my piece is perfect before firing , given it a wipe with a baby wipe and looks perfect. Ive omitted using the brass brush to see if it was that, and scratches still there.

Are there some higher grades of sandpaper or polishing papers |I dont know about?
Am I polishing for too long or too little?

Im at the end of my tether

ps. tumbling is doing a wonderful job, but I is no good for fingerprints (
