Review: Excellent Product - Works as expected. I used it on an outdoor storage box. The water beads up upon contact with the wood now. Use this product in a well-ventilated area. The fumes are brutal. I used it outside, and the fumes still lingered. I used a 3M filter mask when applying it, but still smelled the fumes when I returned to the box to see if it was dry. And the box was outside while drying.
Review: Easy to apply and does the trick - Have purchased other flexseal products in the past, so was anxious to try this spray can which makes it much easier to apply than some of the other products and does a good job of ceiling. Any leaks that you have. I use mine on a corner for a gutter on the outside, and we live in a climate that can vary from 10° below 0 to 101° above.

## Questions & Answers

**Q: Would this work to "paint" the top (not the soles) of a pair of shoes (red)? I need something that has some "give" so it won't crack in the crease.**
A: I have used this product for that exact purpose, works perfectly

**Q: Can you use this product on canvas or hvy nylon?  I want to spray inside of a oudoor back-pack to keep it water-tight**
A: Yes, you can use this product to seal the inside of the bag. I would not recommend spraying into the bag. Turn the bag inside out to apply the product to prevent the build up of fumes. Use multiple thin layers to coat the bag once you turn it inside out. Allow time for the layer to dry before applying the next. The Product will fully cure in 24-48hrs.

**Q: The rock panel under the doors on my truck are badly rusted out like swiss cheese. Will this repair that and if not which product will?**
A: Not sure it would or wouldn’t but From experience I wouldn’t. I used fiberglass to repair my heater channel on a 1970 VW bug and would think that would be similar if you are trying to avoid cutting out and adding new sheet metal.

**Q: Could it be used as normal paint for any wooden furniture like tables and chairs, would it make the furniture feel rubbery? Would it make it waterpro**
A: it would feel rubbery but waterprof,not sure on wood,works great on metal
