Using this 3M 425 aluminum foil tape is easy. Just cut the tape to the desired length and stick it on the surface you need to seal or insulate. When applying, make sure the surface is clean and dry for better adhesion. Be careful not to stretch the tape too much as it may affect its performance. For storage, keep it in a cool and dry place away from direct sunlight. If the tape gets dirty, you can gently wipe it with a dry cloth. This will help maintain its effectiveness over time.
