It worked on a pinhole fine but I watch the container over time change into a ball of rubbery gunk and I did not like having that inside my tires. Lastly 3) aesthetics were terrible. I wanted and got a skinwall version but over a short time they darkened to essentially a black wall.

the difference in ride was indeed dramatic when I first rode a new set of Vittoria Corsa G+ 25mms. Heaven. Even better when I setup another wheelset with 28s. I got two actual flats on this brand —over a lot of miles so no worries—but I noticed whenever the road was wet the tread picked up road gunk too easily.

so I tried Veloflex Vlaanderens in 27/28mm size. My favorite all time now. None of the tackiness on wet roads and sublime ride quality.

but again these are personal choices. Like one may like a race care that telegraphs every bump in the road or another a smooth riding town car for Sunday driving!!

(neither of these ride like town cars by the way)

I learn best by doing. I really over thought the flat tire thing. (I hardly ever get them.) Read advice all over and was real scared about getting one. ;-). In the end I got rid of sealants because of the above complaint AND I observed a friend (riding a gorgeous 70s De Rosa which he raced back then) casually whip a flat tubular tire off and flip a worn spare back on faster than any club clincher rider ever could.
