eDead V1 (no one being produced) was fine for me? Yes, I noticed asphalt smell, but not after a few days, even in extreme heat.Another problem with asphalt mats is the smell. You should be fine during cool weather, but on a hot day, they tend to smell like, well asphalt.
Peel & Seal and Jiffy Seal are roofing products that fit in this category. Many people buy them for sound deadening. Of the products I tested, B-Quiet Extreme, Brown Bread, Dynamat Original, eDead v1, eDead v1SE and FatMat are in this group. Many people report great success with one or more of these mats. They are certainly the cheapest option. If you know your car will never be exposed to extreme heat or cold, they may work for you. I'm not suggesting that all of these products have a 100% failure rate under extreme conditions, but I do believe they are risky. Their narrower temperature range also means they will be less effective the farther they get from room temperature.
I would not use any of these products in my car.
It is now. (V1se)eDead is a butyl based mat.
No it isn't. Please stop saying that.
