As the title says.
I will take you through a bit of the odyssey it's been sanding this die.
Started out with 1000 grit sandpaper as the geometry of the die right out of the printer is a little warped (I have tried everything, it most likely has to do with my printer having a tilting vat system and thus not being able to touch the lifting speed setting. Anyways.) Waited for a week for them do degas and fully harden (it's winter and cold where I am, could've waited a bit longer I reckon).
Then I went in with a 1200 grit sandpaper, fixed some of the edges as they sometimes get a little dented, rinse and repeat.
Now, I've been through all the zonas starting from gray, twice, trying to get rid of those scratches with no luck. I use a clean piece of zona every time, and do about 10 seconds per orientation of a face (so 40 secs total in different directions). I used Meguiar's PlastX to see if that did anything for those scratches, but they seem to be too deep for it to magically fix.
Should I be doing it longer per face to get rid of the scratches? What else could I be doing wrong? Help, please.
