Except that a glass-smooth surface, depending on the paint 
texture, could yield a hot spot toward the projector axis? Even a 
fine fabric texture, though, may reduce this effect. Coarsely 
ribbed or lenticular material would probably negate a silver 
screen advantage, the fine detail that can be resolved.

Fwiw, here's an aluminum paste paint that works quite nicely 
(don't know if it's ideal): Kurfees (brand) Rustplate Aluminum 
Paint, "Bright Metallic", 475/95. This was $2.99 a quart at a 
discount store. The vehicle is linseed oil and resin based, takes 
a couple of days to dry, and didn't stiffen the synthetic fabric I 
sprayed it on. Don't know how it will hold up over the years in 
terms of flexibility, but so far so good.
