Pros Fast acting. Heavier solids work effectively against larger holes. Holds higher pressure. Included valve tool is wonderful.
Cons Solidifies in bottle over time, and no indication of shelf lifeexpirationuse by date is given on the bottle. Nozzle prone to clogs after use. Long bottle awkward fit for shorter seat bags. Will damage the finish of wooden floors.
I usually ride Tufo S33 Specials at 120 psi. They've been great, so great that when I finally did get a flat, most of the sealant (which I bought 6 months previously) had solidified inside the tube. There was still enough to do an effective job - thanks, Tufo - and the tire's still holding 120 psi after another 250 miles.
Exposure to air will solidify this stuff pretty quickly. While repairing on the road, I injected some, set the bottle aside, and inflated the tire. When I found I needed a little bit more, the stuff still inside the nozzle had solidified. Fortunately, the wire used to tie the valve tool to the bottle came in handy at reaming the nozzle out.
So I like this product, but I'd like it more if there were some sort of expiration date, which is the reason for the two stars' value rating. My next tube I'll probably seal in a zip-lock bag to add another layer of protection.
Finally, be careful of spilling this stuff on hardwood floors. If so, clean the floor immediately. Should you keep your bike indoors, put some sort of drop cloth under the repaired tire. I spilled some on a hardwood floor, found it soon afterwards, and it had already stripped the finish. That's my fault, not Tufo's, but worth knowing.
Thank you for your feedback.
