Use caution when handling the Auto Tack Mat as the tack pins are very sharp! Nevertheless, the Auto Tack Mat is simple to install. The mat is cut with scissors to the size and shape desired, and it is installed using the double-sided adhesive provided. The adhesive squares can be cut in half to accommodate installation in smaller spaces.
Before installation the engine surface needs to be cleaned where the Auto Tack Mat will be positioned. The engine surfaces can be cleaned with damp paper towels and an ordinary household cleaning product; surfaces should NOT be cleaned with any product that leaves an oily residue, as this will interfere with the adhesive needed to secure the Auto Tack Mat.
The highest priority areas to cover with Auto Tack Mat are any level areas adjacent to wiring. And mice can occupy even small spaces in an engine, so be sure to evaluate any area located next to wiring.
