So Richard's experience was a noticible increase in noise through the floor. And Steven's was just the opposite. My truck is so blasted noisy as it is, this probably doesn't really matter, but...

I'm wondering if the choice in lining material makes a big difference. Richard, how much of the undercoating/sound deadener did you use? Was it sprayed wall to wall on the floor? I'm wondering if the Line-X just does a better job of attaching to the sheet metal and absorbing vibration. I know the stuff is the harder/stiffer of the professionally sprayed liners. Maybe that makes a difference.

I know we've talked about this before in years past. I was thinking it would be perfect to lay down some material like dynamat (or other, cheaper alternative), then spray a liner in over that. The mat would smooth out the seams and such in the floor pan, and the liner would seal all the cracks and such.

I don't know if the liner would stick though, and if it didn't you'd be left with a huge mess. Steven, does the Line-X look like it would hold up sprayed over a layer of dynamat / asphalt type stuff? This just seems like a bad idea to try out.

As for the wiring looms, they run along the door sill, so I like the PVC idea. I think a piece of PVC cut in half length wise and set over the loom (attached to the floor somehow) would be good protection.
