The Inland "silver" is pretty much a grey. Hatchbox silver PLA is a bit darker, and more silvery.

I didn't do any post processing Came off the printer like that. It did have support under the plate, as there is a recess in the middle over the switch, so I removed those, but thats it. I did have to glue back one of the small prongs that broke while removing it from the bed. But that is probably a PLA thing, more than a printer thing. More brittle, and parts made vertically will always be weaker due to the layers.
