James I tone down the gloss using a product here in Australia called Long Life High Gloss Floor Polish. I guess it is similar to Future which i cannot for the life of me find here. I mix it 6 parts polish to one part Tamiya Flat Base (XF-21). That ratio gives a finish that I like.
Przemol, for the prop, it is painted. I use the RB Products laminated prop mask and airbrush very thin paint, misting the layers and build up the finish.
