Big cam, big boom
By: Robert Chisholm on 3 February 2021
I built my car when I was young and stupid. Wild cam, loud exhaust, no insulation. Mistake. It was unbearable to drive for anything over 15mins because of vibration and boom, A quick call to car builders and I was equipped. After installation of the Car Builders sound deadening as recommended, I can now drive the car regularly. Its still rowdy on the outside, but good on the inside. I can even hear my music.

Under Bonnet Insulation

Great product. Easy to install. Super sticky to prevent unfeeling. Also, insulating material is common through complete thickness. Ie- no layers to come off due to engine heat.4/11/2020

Under Bonnet Insulation: I thought it wasn't going
By: Matt on 19 October 2020
My aim was to reduce cabin noise in my Vito. I installed it under the bonnet, following the YouTube instruction video. I was pretty disappointed to find that the cabin noise level had not reduced after installation. Then I looked in the engine at all the sections of metal sheeting that lay between the engine bay and the cabin. So I set about cutting lots of small pieces to fit into all of the unusual little spaces on the back wall of the bay. Having done this I was delighted with the result. It has made such a difference. I'm very happy that I bought it (and had a second crack at installing it where it was most effective).19/10/2020

Thanks for the tip!

I was absolutely amazed at the noise reduction, I reckon it is at least 10 decibels quieter and the job is not finished....... Just a great result so far, really happy with the product its effectiveness, its ease of install and its look. The truck mechanic had a look and he knew of the product, he was amazed at the result and how neat it looks, so you have a convert already, but it sells itself..21/3/2017
Under bonnet insulation for my 1965 Wolseley 24/80
By: Trevor & Heather Modistach on 13 October 2016
First, your delivery was exceptional, 2 days from order to our front door in Sth. Aust. The Installation was a bit daunting as the Wolseley bonnet is one continuous slab of metal with bracing around the edge, raised approx. 10mm with a raised pressing going from almost flat at the rear of the bonnet to deeper at the front to match the grill, with a cross brace across the the bonnet toward the front. To be able to tuck the insulation around the edge under the 10mm gap of the bracing, to give a really neat finish, I cut the insul. approx. 15mm wider than required, and with the 'Olfa' type knife supplied with the kit,I cut through the backing, leaving approx 25mm around the edge where the backing would remain,to allow me to slide it under the bracing once the rest of the insul. was stuck down. I also cut, just through the backing, from front to back, dividing the width of the bonnet by 4 so we could start sticking it down in sections rather than pealing all of the backing at one time. we started from the centre of the bonnet and worked out to both sides. Because of the front cross brace, I decided to join the front section at the back edge of the brace, as there was no-where to tuck the edges under so it had to be cut the exact shape. I am wrapped with the end result. As all that was under the bonnet before was approx. 3mm thick cardboard type 'stuff',this not only looks great, but has to be a huge improvement over the original. The job took just over an hour, and once we worked out how we were going to tackle it, it wasn't daunting at all. We had the bonnet off the car to do it. (photos forwarded by email )13/10/2016
