I've got Rustoleum Bedliner on my rig, and tested a spot on the hatch with air craft stripper. Came off with the wipe of a cloth after letting it sit for about 15 minutes. There was some residue left, but it was because the stuff turned into a paste.
I plan on getting a gallon or so of the stuff and stripping the truck in preparation for the paint job I'm going to be doing.
And just saw the date on this. Freaking tapatalk making things look like they're new when they're at least two months old. Guess I should pay better attention to the date in the corner, huh?
I'm not sure about Rhino, but I have removed Line-X by sticking a crowbar under a corner and pulling up on it, then prying the rest out with the crowbar.
