This deluxe ONE piece bonnet pad is made from a material called "Hardura" which has a heavy duty PVC skin with a felt backing. It is designed, as you can see, to cover the whole inner section of the bonnet and we have also quilted the material to give it that handcrafted look. The kit also includes a high temperature adhesive and fitting instructions. This kit will make a huge difference to noise and engine vibrations. Takes about 20 minutes to fit - however you need to let the adhesive really dry for 24 hours. We suggest that you remove the bonnet from the car to carry out fitting.
