As you know I received several Rambone samples from the pre production run, amongst them a few made from super solid high glass fibre material. Those are pretty much unbreakable, but they look... ugly. The surface is very rough. I tried to polish it, but it does not submit itself to polishing very well. The material is just too uneven. So... I polycoated it, just like it would be made from wood. Then of course the polishing is well possible! I am really happy with the outcome. The piece is so glossy black that it looks wet even if bone dry. You may say it is a waste of time to polish a piece of plastic, but I actually like it a lot!
