Review: Works like it should! - I’m using this to try and reseal an air bag for one of my baggers on a rat rod. Had a large leak in one and very slight leak in another. The slight leak seems to hold but I’m experimenting with the large leak. Trying to keep filling and let it set for a cple of months then fill it again before I attempt to add air. I’ll post an update. But for small leaks it seems to work well.
Review: Great for everyone with a shop. - This product always comes in handy on the farm.

## Questions & Answers

**Q: Will it mix with other tire sealers**
A: When I purchased this awesome tire sealer, one of the cautions was, don’t mix with other sealers. Why, I can’t answer that other than it might be possible for a  chemical reaction of some sort. Or hamper with the effectiveness of sealing leaks. When I get too my ranch barn I will inspect container warning label and see if I find any useful info and get back to ya.

**Q: How much do you put in each tire?**
A: I used a half gallon per tire.

**Q: Is this for tubed tires?**
A: The Bulletproof-Grade Ultraseal can be used in tube type tires but the Ultraseal Extreme is a better product for that application. It is specifically designed to be used in tubeless and tube-type tires. You can find that in our Amazon store as well. Thanks for your inquiry -- Gempler's Technical Department

**Q: Will one gallon do a zero turn mower?**
A: The amount used per tire is dependent upon the tire size. Contact Gempler direct and ask for a tire chart to ounces of product.

### ⭐⭐⭐⭐⭐ Gemplers super tire sealant.
*by P***S on April 20, 2021*

Product works great. I placed it in the tires on several atvs that are operated in terrain with thorns and sharp rocks. The tires previously kept getting penetrated and going flat. After adding this product, the tires self seal.
