How do you Sand Coloured PETG without loosing the Colour? Are there any Methods to Preserve or Regain the Colour? (lemmy.blahaj.zone)

After Having experimented in Making Perfectly Smooth Surfaces for about a Year now within the Print Process itself, Its time I Capitulate and start putting in some more Work and Sand it all smooth!

Just a bit of an Issue... Whenever I sand Coloured PETG, it looses its Colour and turns into that Broken Plastic White.

As someone who hasn't had to Fix something like that before, I'm not sure where to even start Fixing this? Can it be Avoided in the Sanding Process, or can the Colour be Regained afterwards?

I have heard of People Treating it with Heat and Vasaline to get the Colour Back, what kind of Methods do you all use and how reliable are they?

I have tried using a Regular Soldering Iron to smooth out the surfaces, to not a lotta luck tho. At what temps can the Plastic Colouring be regained? Because I think I had mine set too high

I've used my soldering iron at 200c to re-attach broken off pieces, to much success.

Edit: it strengthened the layer to layer lines as well. Pretty neat for small bits.
