## Questions & Answers

**Q: I just sawed my boat in half.  How many rolls do I need in order to tape it back together?  The infomercial doesn't specify.**
A: Measure the longitudinal axis of your boat and multiple by two (inside and outside strips). Since each roll of Flex Tape is 5', divide your initial quantity by 5. If the quotient results in a remainder, you must then be prepared to purchase an additional roll of tape in order to account for this extra distance. Use the remainder as the subtrahend and 5 feet as the minuend to determine how much excess you will have. This amount of excess tape will allow you to complete other invaluable projects, such as lifting 25-pound weights off the ground or repairing the gaping hole in your roof from big storms (which cause big damage). Hope this helped.

**Q: Can this product be used to patch a 5inch round hole in a boat tarp?**
A: Many people have had success using Flex Tape for this application. We recommend applying it to both sides of the hole and make sure it reaches 3 inches over the area on each side. Apply lots of pressure after application. It may only be a temporary repair depending on the material.

**Q: Patio brick blocks moved away from the (vinyl) siding of the house causing leak. How well this sticks on brick and vinyl, to resolve my leaking?**
A: Hello Mohammed ,Thank you for you inquiry. For this type of application, we recommend using Flex Seal Liquid, which can be found here: https://www.amazon.com/s/ref=nb_sb_noss?url=me%3DA1TTB2MXHGYRTJ&field-keywords=flex+seal+liquidYou can either brush, roll, dip or pour directly into/onto surface.

    Very Sticky
  

*by A***R on Reviewed in the United States on 4 October 2023*

The product was great.  I had two rubbber backed rugs I needed to put together. Every other tape, including regular duct tape, would not keep them together.  This product was perfect.  It was wide enough and the adhesive is great.  Be careful when getting it off the roll because when the tape sticks to itself, you will not be able to pull it apart.  Use very sharp scissors if you need to cut it.
