Boy you hit the nail on the head with that. In hindsight I wish I tackled one or two projects at a time and kept it on the road instead of changing everything and tripping over truck parts for years.

It requires 2 types of seam sealer to get it done the right way. The stuff I used yesterday was the free flowing self leveling type. I only filled the rails to where it starts to drop off at the back of the cab. When it made its way about 1/2 way down I just ran my finger and smoothed it back upward in the channel. Next step will be a full bodied seam sealer which stays where you put it. I think if one was to raise the cab high enough in the back to keep it from running down the back at all, the sealer would pool up at the front and possibly run over the edge of the rail.
