Seal Fender Flares with Automotive Rubber Seals

When replacing or adding fender flares on your vehicle, fender flare trim mounts between the body and the flare. This automotive rubber trim helps your fender flare fit tightly against the vehicle to minimize vibration and gaps while providing an attractive finish. Explore Trim-Lok’s fender flare, made of ozone-resistant EPDM with a 3M automotive-grade tape and designed to easily fit most fender flares. Fender Flare Trim also prevents small rocks and debris from getting caught in the gap that cause damage like scratches to the body, which can lead to rust and corrosion.
