I linexed my truck. Was abrehensive at first but after some reading and finding out that Line x is pretty much indestructible and 100x stronger then the OEM paint I have it a go.
You have to remember that linex also strengthens the bed as well. I wouldn’t worry a bit man. The rest of the truck will rust away before the bed will!
