Found this stuff at WALMART - RUSTOLEUM TEXTURED FINISH. I tested it on other stuff before I sprayed a flashlight with it. Very durable. Hasnt flacked off yet.I sandblasted the finish off of the ULTRAFIRE WF602B center sections and then applied the finish. You have to spray at a distance to keep the coating thin. I also did a HUNTLIGHT FTA2 without sandblasting. I carry this one daily. Also did a section of the handle on a MAGLIGHT 5- C. It really helped in holding on to the maglight.
