WASTED TIME AND MONEY January 12, 2008

All I got in return for this was the damage it did to my pocketbook and nothing else. DON'T WASTE TIME OR MONEY LIKE MYSELF. IF SOME CUSTOM RADIO INSTALLATION PLACE TRY TO TELL YOU DIFFERENT THEIR JUST TRYING TO LINE THEIR POCKETS BUT WHO CAN BLAME THE FOR TRYING TO MAKE A BUCK.

... as long as you don't ingest it. Lead sheet by itself doesn't cause any health problems. It's only when you eat it or breathe particles released from grinding or cutting that cause an issue. As an acoustics engineer, we use lead sheet all the time as a means of adding mass damping to ductwork to reduce flow noise. It's cheap and can be formed to complex shapes pretty well. In a car, this stuff would be most effective in adding mass to large body panels (doors, trunk floors, etc.) to reduce the amount of external road noise getting into the car. All they've done here is package it in a convienent form with adhesive backing and added a hefty markup.

The thing comes with a warning about installation procedures as it has a literal layer of lead on the thing! I know that in theory, you put everything on top of it so that it is covered. But, the cabin of a car is generally pretty sealed and I can't help but figure some lead is going to get into the cabin air. At least, I'm not willing to take the chance it won't. Maybe it does a great job, but, I still ain't sticking no lead sheet in the cabin of my car!
So, what I'm going to do is, get a non-lead heat shield from a a heat shield company, like maybe Heatshield Products. And then put some Dynamat or competitor on top of that. It might cost more. Or, it might not, Dynamat products are pricey.
