What is shown in the 3DDC link is pretty

At a recent 3D printer meet up one of the presenters demonstrated what can be done with metal paints over PLA and ABS.
He had aerosol cans of various metals. Tin, aluminum, bronze etc.
A couple models he polished to a high luster others had a patina finish. One model had gold leaf applied by hand.

An acetone vapor procedure was applied to smooth the ABS. He had some magic to smooth the PLA too ... I can't recall what that was ...

Just wanted to point out a nice finish can be done at home.
