Do I need to prepare the original fender before installation?

Yes. Clean and dry the mounting surface on your factory fender, and sand lightly to improve adhesion if using adhesive-based mounting. Check for any existing damage or rust spots on the OEM panel — address those before fitting the over-fender to ensure a tight, flush panel line.

What prep work does the FRP panel need before paint?

Sand the entire outer surface with medium-grit sandpaper to dull the gelcoat and promote paint adhesion. Fill any small surface imperfections with lightweight body filler if needed, then sand smooth. Wipe down thoroughly to remove all dust, then apply your chosen primer and paint system.

Will these over-fenders affect my tire clearance or suspension travel?

Over-fenders sit on top of the factory panel and do not intrude into the wheel well. Verify your tire diameter and suspension setup before finalizing installation to ensure the flare profile clears your sidewall at full articulation and during turns.
