Dynamat

I have no smell whatsoever. I didn't use the aluminum tape anywhere. It is thick and somewhat pliable. It took some doing to form it into the contours of the floor. The roller helped a lot. At some spots I would slit it so I could roll it into a contour better, then I would lay a strip over the slit. Pretty easy, and now that I finally have the shifter with all the console pieces installed, it is much quieter. The doors are next.
