Ensure that both left and right hand Fender Flares suit the profile of the vehicle. Note the areas where the Fender Flares
come in contact with the vehicle. NOTE: Before fitting Fender Flares remove any moldings, strips or existing flares from
the wheel arch. If there is a body side molding, mark where the molding is to be cut, alternatively the Fender Flare can
be cut to go around the molding. Be sure to allow enough room for the extrusion.

*PRIOR TO ANY PAINTING & INSTALLATION, PRODUCT SHOULD BE THOROUGHLY
INSPECTED FOR ALL COMPONENTS LISTED ABOVE. PRODUCT SHOULD ALSO BE TEST
FITTED PRIOR TO ANY PAINTING & INSTALLATION. PLEASE CONTACT SMITTYBILT IF YOU
HAVE ANY FITMENT QUESTIONS AND OR MISSING COMPONENTS.

PAINTING INSTRUCTIONS – If Fender Flares are being painted; do not install edge extrusion until painting is complete.
Prior to painting, clean all surfaces to be painted using clean water and a mild detergent, do not use lacquer thinner or
any solvent based products. Wipe completely dry. Best results will be achieved by wiping the areas to be painted with a
tack rag just prior to painting. Most automotive paints can be applied directly to the Fender Flares, however some may
require a primer (check paint manufacturer specifications). Good adhesion will be achieved without sanding. Select a
paint (and primer if necessary) that is suitable for rigid plastics PMMA (Acrylic). If using a paint system that requires
baking, do not expose the product to temperatures above 70°C (158°F). Do not fit the extrusion or any of the hardware
to the Fender Flares until the paint is completely dry.

Please read instructions entirely before installing this product.
