The 6 Best window Seal putties (2023 reviews)

The features department is where 3m window seal putty truly manages to shine. Whether you're protecting your hardwood floors from paint splatter or going all out with a decorative mural, rely on scotch delicate surface painter's tape for a professional look that's easy on your surfaces. This Ribbon Sealer is a perfect match to the sealer BMW uses to hold the foam vapor barrier. It can be used as a seal between the window and framework that secures to the vehicle. This roll of sealer comes with a sufficient amount of material to replace one windshield or backlite. It allows you a lot of working time until its pressed firmly against the door.

This stuff does not like to come off of anything, which is good for sealing windows. This will seal the window and make it waterproof however if any of the material is visible, it is very tacky and will remain tacky and pick up dirt.
