Our 3M™ Sealing Strips are made of soft butyl rubber and quickly and permanently seal all types of seams, joints, and openings – long-lasting bodywork care and repairs in significantly less time.

Thanks to the durable butyl rubber and permanent flexibility, our 3M™ Sealing Strips are ideal for sealing hidden joints, seams, and gaps. This thumb-applicable sealant is ready for immediate use without mixing, spraying, or tools. The product can be quickly pressed in and smoothed with your fingertip. Thanks to its high heat resistance, the product is also suitable for seams in the engine compartment and for splash guards. The 3M™ Sealing Strips do not harden or become brittle; they remain pliable, and the gaps are permanently sealed. The product also does not shrink, making it ideal as a sealant for filling holes, reducing noise levels, and preventing moisture intrusion. The ready-to-use product is available in convenient 30-cm lengths by the box. The product can be applied in minutes without tools. The product seals seams and gaps and also protects against noise and moisture—even at high temperatures. Thanks to its long-lasting durability, touch-ups are reduced to a minimum, saving time and money.
