## Questions & Answers

**Q: Is this product UV rated?**
A: The tape is UV resistant and can withstand extended exposure to continuous sunlight.  Hope that helps and thanks for your interest in our sealant tape.

**Q: Confused as above in questions it says clear tape is white?**
A: This fantastic tape comes in three colors: white, clear, & black.  For my purposes, I purchased the white tape.   If part of the advertisement indicates clear is white, it’s wrong.  It’s probably a ‘typo’.

**Q: Can the tape be removed without leaving residue on tile?**
A: Unfortunately this is quite strong adhesion and would leave a residue if you were to remove it.  It could be removed ultimately with another cleaning product but hope that helps and thank you for your interest in our Water Proof Tape.

**Q: Is this tape clear?**
A: No our waterproof tape is white.  Hope that helps and thank you for your interest in Better Boat Water Proof Tape.
