Will this lip interfere with the factory front bumper seal or trim?

No. This lip uses the same attachment points as the stock bumper, so it sits within the factory opening without binding or overlapping existing trim. Verify your bumper is properly aligned before installation.

Does the lip require adhesive, or is it bolt-on only?

Bolt-on only. All mounting uses existing factory hardware holes; no epoxy or adhesive is needed. This makes removal clean and reversible if you ever swap it out.

What prep work should I do before installing this?

Clean the mounting area and bumper contact points with soap and water, then dry thoroughly. Sand and prep the lip's mounting surface lightly before bolting down to ensure a flush, rattle-free fit. If you plan to paint or modify the finish, do that before installation.
