Can you polish PLA plastic?

Get a soft cotton cloth, and apply a small amount of liquid polish. Then apply to your 3D print surface in small circles until all the polish is rubbed into the surface. Once you’ve finished that, the surface should look reasonably shiny. The final stage is to buff up the surface into that mirrored, polished shine.

Can you varnish PLA?

Varnish. If you want to save yourself the intermediate step of using a primer spray or a spray filler, you can also smooth your PLA 3D prints directly with varnish. You can use spray paint or paint from a can for this.
