Application
Universal fit with a Honda-optimized profile. Particularly suited to Honda and Acura models where the 9mm channel depth and Honda-style geometry is common. Can also be used on other vehicles where 9mm foam underside molding is appropriate — verify channel measurement before ordering.
What does underside glass molding do?
Underside glass molding seats between the bottom edge of the glass and the vehicle's pinch weld or channel. It creates a consistent seal, cushions the glass against the body, and prevents direct metal-to-glass contact. Proper underside molding also helps exterior trim and moulding sit flush and even around the glass opening after installation.
What is the "Honda style" profile?
The Honda-style profile refers to the cross-sectional shape of the molding, which is optimized to match the channel geometry commonly found on Honda and Acura vehicles. This profile reduces the need for hand-trimming and provides a more consistent fit compared to generic profiles on Honda applications. It can also be used on non-Honda vehicles where the 9mm dimension fits the channel.
What is the difference between EPDM foam/sponge and solid compound molding?
EPDM foam/sponge molding (this product) compresses under pressure, making it ideal for tighter channels, vehicles with slight dimensional variation, or applications where a conforming, forgiving fit is needed. Solid compound molding is firmer and better suited to channels where precise sizing is known and minimal compression is desired. Both types bond to the glass via pre-applied tape.
How much molding do I need per installation?
A typical passenger vehicle windshield requires approximately 12–16 feet of underside molding. A 75-foot roll covers 4–6 complete windshield installations, making it a practical single-box shop supply for technicians who do moderate windshield volume.
Is this compatible with both OEM and aftermarket glass?
Yes — because this molding is cut to length on-site, it works with both OEM and aftermarket replacement glass. Always verify the channel dimension on the specific glass being installed, as aftermarket profiles can vary slightly from OEM. The Honda-style profile is especially well-matched to Honda and Acura OEM and aftermarket glass.
