The Fusion PPF Hornet 4" Paddle Squeegee is the latest in Paint Protection Film installation tools. This triple durometer paddle squeegee offers the handler two durometers to install with. The black install side measures in at a firm but flexible 80 durometers and the yellow side at a softer more pliable 70 durometers. The red "spine " between the two layers acts as a rigid support core for the soft squeegee blades on both sides. Switching between the two install surfaces is as easy as flipping the tool in-hand to the desired working edge. The Fusion PPF Hornet is specifically engineered to be safe for installing paint protection films.
