Will this interfere with the trunk seal or undercarriage at speed?

Front lips mount to the lower fascia and do not extend into the trunk area. Check your vehicle's OEM mounting point locations before installation to confirm fitment with any existing trim or underbody components—minor gaps may require shims depending on your specific setup.

Should I drill through or use adhesive for mounting?

FRP pieces can be fastened either way depending on your preference and the mounting holes your vehicle provides. Adhesive requires thorough surface prep and cure time; fasteners offer quicker installation. Confirm your OEM fascia has compatible mounting points before committing to either method.

What prep work is required before painting?

Sand the surface evenly and wipe down with a tack cloth before applying your chosen primer and topcoat. FRP requires standard automotive prep—follow your paint manufacturer's recommendations for adhesion and cure time. The surface accepts most modern automotive finishes without issue.
