Quality Automotive-Grade Foam

3M™ Rigid Pillar Foam is a two-part urethane material which foams in place (closed-cell foam). It can be applied to areas where OEMs recommend rigid foams such as pillars, sills, doors, floor pans, roof bows and other automotive body cavities. Use it wherever OEM rigid foam is found.

Easy to Work into Difficult Places

Working with this pillar foam is a breeze. It easily flows into and fills all cavities without the need for technicians to work foam into hard-to-reach areas. It effortlessly flows to fill challenging spots. Once in place, it expands 10 times its original volume to fill large cavities. You only need to use a small amount of material to fill a large area.

Replicates OEM Appearance

For OEM replacement of rigid foams, use this foam to closely mimic OEM performance. Using this product helps to restore the vehicle to its "pre-accident condition".
