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 would say clear coat it, but if you’re doing that, you might as well paint it and I know that may be more than you want to get into.
My process is covering with a light coat of plastruct, sand it (around 800 grit usually gets it done), prime it, then clear coat and it usually looks better than new. Clear coat alone will go a long way.
