Q: How long does butyl tape for car windows last on a vehicle?
A: Usually 15 years. It won't crumble or lose adhesion like cheap weatherstrips.
Q: Can I use this on a heated rear window with defroster lines?
A: Yes. Just apply the tape beside the lines, not directly over them, and press gently.
Q: What if I need to remove it later?
A: Cut through the tape with a fishing line or a trim removal tool. Then roll off the remaining butyl with your thumb – it balls up nicely.
