Tricky but worth it.

Definitely a two person job on an MGB. Managed to put it on in one piece, under the centre brace!! Tricky job but the video is well worth watching.

bought this for my Patrol as the old hood lining was long gone, looks good and works good! even covered up up the evidence from the larger bonnet scoop install :):)


old style Troopy revamp

This is a great under bonnet replacement to the falling down mess that was there and couldn't recommend it more, only thing i could ask for is a bigger sized sheet to maybe 1500mm x 1300mm as the 1500mm x 1000mm just wasn't enough to get the front lips of the bonnet, not a problem though as it was more cosmetic than function.


Fantastic - 5 Stars

Very impressed with ease of application and the effect of reducing engine bay noise by this product. I installed this product to cut engine noise down at highway speeds after already installing sound deadener previously. In combination with Stage 4 sound deadening kit, my old tin can Hilux is a totally different car. Pleasure to drive.

I have used this on 4 under bonnets now and it is an extremely good product for making things look “factory” and professionally finished. I am about to order another roll as I have priced an original for my Commodore and this is also cheaper. I also use the floor sound deadening foam and am super impressed. You need to take time and check is in place because once you have placed it then it’s there for good. The glue sticks instantly and does not let go. I recommend this to anyone who is willing to watch the video on line to how to fit it. I watched the expert and it made the finished job so much better.


Under Bonnet Insulation

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.
