This product is used to protect the undercarriage metal jack point railing that is on most vehicles.
Highly durable and resistant to damage, it will keep the chassis rails from getting pinched, bent, and broken.
Polyurethane is soft enough to not harm your vehicle's metal yet rigid enough to support it.
Great for DIY vehicle maintenance or taking one with you in the car as some tire shops do not use these pads, and unfortunately bend your pinch/scrape off paint on the welds.
This can eventually lead to rust, save yourself the hassle with this simple product!
