I saw multiple times the videos from the Car Builders blokes on YouTube, they have great knowledge of their trade and have some very nice products. Being sound deadening products very heavy, shipping from Australia would not work for me. I tried my best to apply the knowledge they share using locally available products.
For what they call stage 1, steel panel vibration dampening, I was able to source foil covered butyl rubber sheets, very similar to what they use on their videos, and I was very happy with the quality of the product. Something sold locally under the name of Technoise. There are a lot of videos online of people fully covering the roof and floor at this stage, but the CB blokes themselves tell this is not really necessary. If you make sure flat steel sheet areas have at least patches of the product, you should be good. I opted for such approach to save on the material and weight, as this is quite heavy.

Then for stage 2, heat shielding and sound absorption, I could not find anything exactly as CB sells. I went on finding closed cell products (for heat) and open cell products (for sound). Found a local manufacturer with several products on their line and a very well spoken technician to explain and provide orientation on where to use their products, how to apply, etc. I ended up buying the recommended product for the roof and sample amounts of every other product they had to see the difference myself. The product I picked for the roof is a soft foam made out of PVC and poly-ure-thing this and that. It is their product with highest heat blocking graduation other then the specific stuff for engine compartment/under the bonnet usage. It absorbs sound as well but the heat part is where it is supposed to ace.

Now I have to wait for the upholsterer to finish the roof lining and install the windshield. After that, he will let me take the single-seater Patrol home for a weekend to work on the floor deadening and then return the car to him to work on the carpet. He has already picked the best parts of two complete seat sets to make just one out of it. Seat structures are already blasted and painted. Yet to start is the foam work and the cover work.
I told him to bin the rest except for something on the driver side for that weekend sound deadening operation.
Door cards are maybe 80% done already.
