If you ever want to sell it, don't line-x the interior or exterior of the tub at all. Strictly paint it as few guys want a line-x'd interior/exterior as its a pain in the ass to remove for work needs to be done and it's not as aesthetically pleasing as paint.

Only ever Line-x or Rhinoguard etc the chassis side of the body if you ever plan on re-sale. In theory it's great to prevent rust etc, but it's just so damn ugly and devalues any vehicles it's used on when it isn't just the underbody or a trucks bed if a work truck lol
