I've abandoned ABS.
I was disappointed with it when I first tried it because I assumed that the FFD materials would have properties close to that of the injection moulding grades and was surprised that it was so soft compared to them - and to PLA.
Then, because I'm usually printing mechanical models (designed in MOI, of course) often I found it difficult to keep the parts flat enough so I've decided to stick to PLA or similar.
Before abandoning ABS I did experiment with Acetone polishing - even had a Magic Box for a while - which certainly could produce a high shine but I found too hard to 'fine tune'.
I'm hoping that the Polysmooth/Polysher combination will have a wide operating window with a material which is easy to print and a polishing process with a lot of latitude.
