Will this lip interfere with my bumper trim or lower valance?

The AF-2 lip is designed to sit flush with OEM bumper geometry. Before installation, dry-fit the lip and inspect clearance at the rocker corners and bumper edges. Minor sanding of the mounting surface may be required to achieve a gap-free fitment—this is normal and expected with aftermarket panels.

What's the best way to prepare and paint this lip?

Sand and prep the surface thoroughly before applying your chosen finish. Many builders prefer epoxy primer followed by color coat and clear protective layer. Because FRP can absorb moisture, a quality clear coat is highly recommended to extend the lip's life and gloss retention.

Should I use adhesive or mechanical fasteners to mount this?

The AF-2 lip can be secured with adhesive or through-holes drilled to match your bumper's factory mounting points. Adhesive alone works well for lower-stress applications; mechanical fasteners provide added security if you anticipate track use or frequent removal. Choose your method based on your build goals and intended use.
