Will this lip interfere with my trunk seal or weatherstripping?

No. This front lip mounts to your bumper fascia, well forward of the trunk area. It has no interaction with trunk seals or rear weatherstripping.

Can I install this without drilling into my bumper?

Yes. The lip uses factory mounting points on your bumper, so no additional drilling or fastener holes are required. Verify your bumper's OEM attachment locations before installation to ensure clean alignment.

Does this FRP panel need primer before paint?

It Requires Surface Prep, which means the surface is prepared to accept primer and paint directly. Sand the panel lightly and wipe it clean before applying your chosen primer and topcoat system.
