I just finished a SIG Fourstar 40 (picture attached) and painted the inside of my canopy with Plastic Enamel spray paint that I got from Lowes. I took my time and sprayed thin coats and let it dry for an hour or so between coats. I think I ended up with about 7 or 8 coats. I think it looks great. It not 'tinted' though so I don't know if this is what you are looking for. I was not going to add a pilot so I just painted it so it would contrast the yellow.
