3M 7000028370 Strip Calk Black 60-strip Box

Product Description

The 3M 7000028370 is a soft, non-hardening strip caulk supplied in one-foot lengths for sealing seams, joints, and openings across a wide range of construction and vehicle assembly applications. The material presses into place by hand and smooths with a finger, requiring no caulk gun or mixing. It adheres to metal, paint, glass, and rubber without shrinkage, remains completely waterproof, and will not dry out or crack over time. Each box contains 60 one-foot strips. The black color blends with dark substrates, and the surface accepts paint immediately after application with no cure wait required.

Strip calk of this type is commonly used by body shop technicians, glaziers, and general contractors to seal panel seams, window perimeters, door openings, and similar joints where a flexible, permanent seal is needed. Its non-sag consistency holds position on vertical surfaces and overhead applications without slumping, making it practical for awkward installation angles. The product is well suited to both shop and field conditions where a pre-formed, hand-applied sealant strip simplifies workflow.

Installation Notes

No tools are required for application — press the strip firmly into the seam or joint with a thumb and smooth with a finger for full contact.
