## 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. It is excellent for concrete, glass, brick, stucco, masonry, wood, copper, plastic, tile, fabrics, wires, vinyl, fiberglass, ceramic, porcelain, metal, aluminum, and natural stones, foam, asphalt, EIFS, TPO, PVC, EPDM, CSPE, Hypalon polyurethanes and so much more!Sincerely,SherylCustomer Care at Swift Response

**Q: Does this stick to asphalt shingles?**
A: Dear customer flex seal liquet should be preferred for asphalt shingle

## Customer Reviews

### ⭐⭐⭐⭐⭐ Excellent Product but with Caveats
*by P***L on December 27, 2017*

Roll has 50 inches of usable tape, not 60 as advertised.Packaging material sticks to edges of tape and efforts to remove nearly impossible without cutting off edges.I got pretty much what I anticipated given the difficulties of working with wide sticky tape.For those looking for estectics, this may not be your best option, but for those of us seeking functional solutions, my taped chair works for me rather than laying out another $500+ for another chair replacement.Yes, there are wrinkles in the tape but I've chosen to think of these wrinkles as giving added character to the chair plus the black tape blends well with the very dark leather / vinyl chair color.I have no doubt that this product is an excellent choice for it's advertised solutions hence the stars.

### ⭐⭐⭐⭐⭐ Very Sticky
*by A***R on October 4, 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.

### ⭐⭐⭐⭐ Strongest Tape I’ve Ever Used - Better get your act together before you eve open the tube!
*by B***E on February 16, 2020*

OK, first let me say this is by far THE STICKIEST tape I’ve ever used. A couple years back our son got in a tangle with a Sonic drive thru sign and creased (actually slit) the rear passenger side door. It’s old but dependable, so we used first black duct tape and later Gorilla tape to weather seal the 15” long horizontal slit. Neither listed very long so I decided to try this product for a change.Holy cow, it sticks to everything. Make sure and have your act together before you try to use it. I thought I did, but my scissors were not sharp enough to get a nice clean cut and I wasted about 1’ of the stuff just trying to get it unwarped. Again, it sticks extremely strong to anything it touches. After prepping the surface (removing al old adhesive), I tried to put an18” long piece on my hot black metal door. I should have parked in the shade and should have also used a soapy speed tac spray like hen I install decals. Anyhoo. First tempt was not great it was cracked and had some creases but had I left it alone, it would hve functioned perfectly.I’m a perfectionist, so I decided to remove the first section of tape and put a new one on. BAD DECISION. This stuff really sticks hard on contact. I made a mess and it took all my strength to get it off. With tons of adhesive left on the door, and only about 12” of tape left, I covered the worst part then used a can of Goo Gone plus some lighter fluid to try to remove the exposed adhesive.Anyhow, for my type of use this stuff REALLY works. II’ve ordered another 5 ft roll and will do y damndest to get it light the next time.
