Under Bonnet Insulation

By: on 1 October 2019
I selected this product to insulate the bonnet of my Nissan Patrol after an upgrade to a supercharger installation. The bonnet required significant structural modification to fit, hence selecting a suitable sound and thermal insulation mat looked like a challenge until I found this product from Car Builders. The material arrived well packaged and I bought the roller as well - highly recommend it. The insulation is VERY tough, and requires sharp scissors and a stanley knife. Working off a template made the task easier. Once the shape is confirmed, simply peel the adhesive cover off, place into position and then using the roller work it into the shape of the bonnet - easy easy work, no wrinkles, and a totally professional looking outcome. I am considering it for a headliner as well, and a number of my mates who have seen the job are looking to do the same as I have done. Highly recommended.
