After I removed my C70's seats & carpet, I shampooed the carpets and then scotch guarded them next day.
While I was looking at the floor pan / uni-body of my C70 I noticed their where sheet steel hollow chambers built into the uni-body. I thought those look like they could be sound boxes "like a acoustic guitar" and sounds could resonate in them. So I stuffed old plastics bags from the grocery store into some of the chambers.
I also cut & laid out some roofing shingles, my C70 is a luxury convertible so it already has quite a bit of sound damping & a layer of inch thick foam under the carpet but I want to make it quieter. Under the foam that is under the front seat carpet is two sheets of sound deadening, but under the seats & behind them their is none.
Under the seats and in the rear seat area I think I am going to lay a layer of thin foam pad and then cement the shingles to the pad, then I will add another layer of cement that I can stick a layer of foam pad to. "So that the whole thing can be removed" - like if I need to do any welding to the floor pan or rocker panels.
I tinted my front windows yesterday and they look good.
The weather looks like its going to be to chilly for me to use the roofing cement tommrow so I might just work on painting my factory wheels that I am rocking on the passenger side.
