Gempler's Commercial-Grade Ultraseal Tire Sealant to Protect Tires from Punctures and Flats, 1-Gallon

Works great

At first I had a lot of apprehension abut the validity of the product because of all the negativity surrounding a competitor's product. I had been plagued with mesquite thorns which voided my warranty on a new tires for my 4Runner. I have a multitude of seemingly endless holes regardless of how many times I've had them patched at different repair shops. Follow the application charts to determine exact volume, remove valve stem and pump the recommended amount. Follow up with air from a compressor to clear any residual sealant from TPMS and to bring the tire to correct pressure. I've not experienced any air leaks at all and would recommend Gempler's Ultraseal over any other tire sealant out there.

This stuff is amazing I use it in all my equipment tires no more having to top off with air once using this product seals everything

Just used it for my leaked tractor tire today and it works good. One gallon sealant come with the pump so it was easy to inject into the tire,

I had added this Gempler's commercial grade tire sealant to 16" load range E tires on my hay trailer as a preventative, filling them as directed on the label. All was well until one tire picked up a very small nail. I pulled it and trusted the sealant to stop the leak. Trailer has two axles and sat empty for a few days and when I went to use it, the tire was deflated. The sealant bubbled out of the hole when I aired the tire to 5O# of pressure. Tire just won't seal. Seems not very "commercial" quality, eh?

I have a small leak around my rim, i applied this stuff 3 days in a row and it still hasn't sealed the rim leak, used almost half the bottle on one tire now , keep in mind this is a small leak, usually takes about 4 hours to flatten the tire, for the price of this I thought it would be a great solution, fix a flat works better than this, even the off brand fix a flat, over $100 for blue water, very bad product , id like a FULL refund, it took me a couple of weeks to make the decision to buy this, because of the price and the videos they have on YouTube, definitely want my money back , also box just came with a few coupons stuffed in it

Messy!

I have used this in my mower tires and tractor tires for years. It works great.
