I recently had my van strippped on the exterior and repainted.  THe bottom 1/4 is Rhino Lining and it was cheaper to do Rhino/LineX then it was to paint.  I am not a painter but my body shop was actually excited when I wanted to rhino line the bottom.  IT saved them time and me money.  I would say that after doing the Rhino.  I would go for the LineX.  Rhino is just some thick burly stuff and line X is more like a rough coating paint.  Just my .02
