Not true. My GMC Canyon had an after-market spray-in bedliner that went over the top edge. I'm assuming they masked off the area and then applied the spray, as the line is 100% straight, and it looked really good. As for scratching the spray...I think you'd have a hard time scratching this stuff. And if it did get scratched, you could probably get it fixed for cheaper than the cost of new bed covers (I think.)
I have the factory sprayed-in liner on my Dodge. I too wish they would have removed the rail covers and sprayed the top of the box as well. At least they can be replaced if they get damaged. The plastic inserts just don't seem to "finish" the appearance of the liner.
Either way, I like my sprayed-in liner and can live with the plastic bed rail covers.
