Started this in a separate post on carpets and wanted to get some more discussion on this subject.
A question revolves around placing self adhering sound deadening material on the floor pans.
Two points have been floated, one being condensation forming between the sound deadening material and the floor pan causing rust.
The second being what happens if brake fluid ends up puddling there.
My thoughts on the condensation is that it would condensate on the outer surfaces, and if the sound deadening material is adhered well to the floor pan it would seal it. I am going to seal the entire floor pan with POR15. I have not decided if I will cover the whole floor pan with sound deadening material (RAAMmat)or do a partial. This is a photo on how that could be done.
Not a TR6 but the idea is the same. Do panels on the area's, such as, most of the floor pan and stay away from the edges, giving rain water or condensation some where to go, what doesn't soak into the carpet pad. Although I am thinking of using some thing that is closed cell so it won't soak up things. Something like backpackers sleeping bag foam.
In regards to brake fluid, I say, I should run a test and see what happens when the butyl substrate will do when exposed to brake fluid. If the RAAMmat were installed so that the ends rolled up the sides of the floor pan it would make a pan that would contain the fluid or let it soak into the pad. I will run a test tomorrow night and see.
Any other ideas or comments on this subject would be welcome!
I use the aluminum foil backed insulation on the transmission tunnel and it really helped with the noise. I plan to cover the outside with the RAAMmat. I an doing the firewall and the insides of the doors and the rear wheel humps and the rear bench. I plan to use the RAAMmat and the bubble insulation on the rear panel in front of the fuel tank and place a layer of RAAMmat on the fuel tank.
I am undecided about the engine bonnet and may wait and add later, just to see if one can notice the difference.
This is a link to other photos on possible ways of using RAAMmat.
Also a link to photo's of my left and right floor pans still in work.
