As a Window Tinter, i thought it would be awesome to just create my own window tint tools the way i would want them rather than spending alot of money on different kids, styles colors ect. this whale tail is awesome. just take some fine sandpaper to the edges and your golden. there is of coarse other things you can do to it, such as add a rubber liner (after print) or before print, add some curves to the handle for better grip. put a hole in handle for hanging on a tool board... i left this one basic and "boring" but the sky is the limit to fit your needs!
