Can I apply Rust Bullet under a Truck Bed Liner?
Yes. Rust Bullet provides excellent surface protection under bed liner material. Apply Rust Bullet according to the application guidelines. As with the addition of any topcoat or other product, if 72 hours have lapsed after the final coat of Rust Bullet, the surface should be etched with Rust Bullet® Metal Blast, or scuffed with 100-150 grit sandpaper or sanding block to ensure proper adhesion of the liner material. This 72 hour period is decreased in areas with higher humidity levels.
