Project Ramp Truck: Installing Sound Deadening

Update by Tim Suddard to the Ford F-350 Ramp Truck project car
May 23, 2017

We have found Design Engineering’s Boom Mat to be light, easy to install and inexpensive. It cuts down on any heat and road noise.
Thankfully, our truck’s floor just had some minor surface rust that we could attack with a wire brush and coat with POR-15.
Just a few dabs of POR-15 on a clean, dry surface and in our experience, rust is gone forever.

With the carpet out of our project ramp truck and the headliner soon to come out for repair, we had an excellent opportunity to insulate the cab a bit more. To do it right we’d have to scrape the floor, coat it with POR-15 rust preventative and then lay down some sound deadening.

While we had no rust at the top of the cab, we did have a bit of surface rust on the floor. Fortunately, scraping it with a wire brush proved the rust was superficial. That meant we wouldn’t have to weld in any patches.

After a thorough job with the wire brush, we vacuumed the cab and brushed on the POR-15 rust preventative. We have used this amazing paint-like substance on nearly every one of our projects and have never seen rust come back.

While driving the truck before, we had noted that our floor was getting warmer than it should. That wasn’t too surprising since the factory insulation was marginal.

We decided to put Design Engineering’s Boom Mat down in the entire foot well area. This lightweight, relatively inexpensive material is a great way to cut down on noise and heat. Bonus: The tin material is not detectable once we put the carpeting back in.
