The biggest improvement....the interior. I've been gluing and getting stupid high on the fumes of industrial contact cement for the last week. The last pieces were laid 24 hours before I took this. The bags in the footwell are part of my secret sauce: each has 25lb of pebble sized crushed rock in it. After a section has been glued and then rolled with a small roller to precisely conform it to the contours of the car, the bags are placed on the freshly cemented section to make sure that the carpet STAYS conformed to the irregular sections until the cement sets up.
