## Questions & Answers

**Q: How strong is this glue?  Can it be used to reapir a crack in 1 galon water  reservior?**
A: I would think so, I used it on a conical fermenter for my beer brewing and its worked fine for a few years now.  No major pressure on it, just 7 gallons of product.

**Q: Can it be applied to a jar to store food in?**
A: I'm not sure, I can tell you its ratted Food Safe. I used it to seal a crack in a conical fermentor I use for home brewed beer and cider. worked fine and left no taste that I could tell.

**Q: (white) what is the texture of the surface after cured?  smooth?  gritty?  matte? shiny?  how can it be made as smooth as possible?**
A: To make as smooth as possible: after you apply the stuff, spray some water with soap (detergent/shampoo works) and smooth it out with your fingers... this method works great for corners and joints where a bead is required.... will probably make a not so great job on a flat surface :-)

**Q: is it dishwasher safe?**
A: The package says its temperature range is -62ºF to 350ºF. I don't know how hot a dishwasher gets, but it might be ok on the top shelf.

### ⭐⭐⭐⭐ Worked For My Purpose
*by W***A on January 9, 2026*

This product was recommended for filling a crack in a refrigerator, so I used this for that purpose. I used it while refrigerator was running. Dried fine; dry time unknown. Worked for that purpose. Not a fan of the shine when dry since the repair sticks out, but it worked.
