Hey guys, I tore the carpet out of my jeep, sanded the metal, and my question is, do I have to sand all of the noise dampering/seal stuff around the edges and back seat area, or will the bed liner just stick?

I've got upol raptor spray on.

 

If I were you I would remove as much as possible. If not that will be the first place it will start to peel.

 

That would make sense. Appreciate it!
