Here was that roller I used to install the matting.

I’ve always been hesitant to use the stick on stuff, mostly because I’m worried that it will trap moisture and rot out the floors. Since my truck sees a lot of mud and dirt I want to be able to hose it out.

I’m a long way from bodywork at this point but when the time comes I think I’ll probably use the lizard skin products from underneath so I can keep a relatively “stock looking” metal floor inside. From there, I’ll probably lay down some sort of rubber Matt.

My only concern with Lizard skin is that I have no idea how robust it is, or how it will hold up exposed to dirt/rocks/road debris in the long run. I may cover it with bed liner or undercoat but I also worry about adhesion of the undercoat to the lizard skin an the application of so many layers of thick pain products fighting gravity over the years.

I’m interested to see where this thread goes.

I sanded to bare metal, applied Rust-oleum Marine coatings primer and paint. Then I laid down over the entire floor a layer of firewall insulation (a product made from recycled denium) that I purchased from Summit. After that I laid down and cut in place a rubber backed walk off/entry mat. And finely placed the original Toyota mats on top. Much quieter and the cabin temps are now way cooler!

My worry with that recycled denim material is that it looks a lot like the sort of material that rodents like to nest in. I'd like to avoid giving them the ingredients for a happy home if I can help it.

@pigmony any updates on this?

for the first restoration I had used 1.5cm sound-absorbing material with a carpet glued to it, now I use 2mm bitumen instead.
The first had worked very well, very quiet, now we give the results, but there is still a long way to go.
I preferred to use bitumen because I will use this 42 off-road and I think it's easier to clean and it doesn't absorb water

@Hungale That looks really nice. I was wanting to do something with my wheel wells in the back and
this looks very interesting.

Are you showing us the earlier restoration in the first photo with the seemingly more absorbent material and
then the later restoration with the black mat?

Is that just loose carpeting over the sound deadening material or are you glueing it in the latest resto?

Edited this post to get some picture clarification.

 

[Hungale]

I don't know what the sound absorbing material is called, but there are 2 types, one soft and one "hard". I used the "rigid" for the rear, and I glued the carpet to it, so it doesn't fold.
It practically stays stuck, I shaped it to precision.

That sure is a pretty floor to be covering up!

I’ve often wondered while reading the sound deadening threads whether the chance of it holding moisture should really be a concern to most of us. I only have rubber floor mats in my 40 and I take pretty good care to keep it dry and clean. I am 56 years old so if I ever decide to make it quieter which I have considered. In 20 years I don’t think I’ll care whether it held a little moisture or not.

@Hungale If you don't mind me asking...could you post up some pictures of your refurbs? In particular I'm curious what you are doing with that dash on the blue one. It seems you've cut it completely out and I'm curious what goes there. As @70fj40 says..... "thats a really pretty floor"
