We recommend drilling all the holes for the rail system 5th wheel,spraying Ultimate in the bed, and mounting the rails on top of the liner, and tap the 1/2" bolts through for a nice seal, and then tourque the nuts to 90 foot lbs.
On goose necks, plate mounted...mount the gooseneck and we spray over the plate up to the tie downs. On mounts under the truck, mount the goose neck through the 3" or 4" hole, and then we seal and spray around the mounting which makes for a great looking job. We also install these hitches.
