I've been experimenting with painting on matte Mylar lately. Matte Mylar is a basically a sheet of semi-transparent plastic, typically used as drafting film.
Painting on this surface requires that I work VERY quickly, as the drying time seems to be cut in half.
Right now I'm trying to get away from tightly rendered paintings that record every little detail, and move towards more painterly, gestural work—with smaller pockets of more refined brushwork. Working quickly aids me in this quest because the paint drying time sort of precludes working at the slower speed all that detail requires. But it allows me enough time to still work in a realistic style...just not straight up "realism."
Mylar also forces me out of my own head...where all my little negative, judge-y thoughts live, since there's not a whole lot of time to second guess myself. Which is a great bonus.
Definitely looking forward to doing more of these Mylar pieces. Here's an approximation of the piece's size in a room (would require a frame):
