Do I need fasteners or adhesive to install this?

No fasteners or adhesive included or required. The molding clips directly into the factory mounting points on your tailgate — no drilling, no modification to the truck.

Can I paint this before installing it?

It's easier to install first, then paint or powder coat after the molding is clipped in place. That way you avoid masking around factory attachment points and ensure a clean edge at the seams.

Will this fit if my tailgate has been replaced?

This molding relies on factory mounting points. If your tailgate is aftermarket or heavily modified, test-fit the molding to confirm the attachment points align before committing to paint or final installation.
