Is this a good product for resurfacing a tent floor? If so, should I do the whole floor or just the areas where it's clearly peeling?

Yes, it can reseal a tent floor, but my experience is that the product directions do not yield good results. I recommend first washing the tent floor (bathtub and dishsoap), rinsing well, and thoroughly drying. Next, wipe the floor with a rag dampened with alcohol (do not use rubbing alcohol which contains oils), and remove all old sealant that is peeling. The alcohol will turn areas that are not sealed dark, note these areas. Apply the Tent Sure with a clean microfiber cloth wiping it on as thin as possible, working in small areas. Let dry 24 hours, then recoat with very thin applications using the cloth. Multiple thin coats are far better than one thick coat. I've had excellent results with tent floor and fly using this application method. Using the built in applicator to apply the product results in a thick, sticky mess with less than advertised coverage. It is possible to apply Tent Sure just to spot areas, but my experience has been it is better to completely reseal the entire surface. Hope this helps.

Can this be used to restore the inner coating in backpacks?

Absolutely! This water-based product is a wonderful sealant traditionally designed to be used on tents ... but it works wonderfully well on many other fabrics to include the inner fabric of a backpacks! In fact, I recently used this product on one of my old backpacks. Of course to work its best, you must first remove any deteriorated waterproofing that may exist from your backpack inner fabric. Once the material is clean and dry, you may apply the Tent Sure product on the fabric. For added waterproofing of your backpack fabric ... I also recommend applying a spray type waterproofing to the outer fabric too! There are many types of spray waterproofing available either online or at good camping supply stores. I hope this helps you! Happy New Year! K.C.L.

can this be used on old jackets?

Sure, anything that is no longer keeping water out.

Kelty customer service recommended this for my tent bottom. Do I apply inside or outside, or both?

Thank you for your question. The directions on the bottle recommend you apply it to the inside of your tent.
