Here at the Main Trophy Supply URL do you all buy the buffed bright, brushed/satin, or opaque aluminum? Or is there no difference?

It looks like in the Rockland kit it is the brushed/satin. I bought buffed bright for the class. We sanded it lightly with 600 grit sandpaper and cleaned with sodium carbonate, and adherence was pretty good for most who were careful, but I am thinking it would be best to use a varnish or maybe buy the brushed satin type.

Second question: do you sub it with polyurethane spray glossy or semi gloss varnish or gelatin? Or nothing? 

Jill Enfield uses metal plates sprayed with flat black paint I see...
