Had a 25 year old wheelbarrow tire that leaked like a sieve (sat outside all that time). Just as an experiment, I dumped some Slime in it and filled it with air. Used it last summer to move bricks for my driveway. Thing still has air in it. I was amazed. Ride-on is similar to Slime and Fix-a-flat but with fibres. I have never seen it for sale in Canada.

I have used slime for years.. from lawn tractors to 4x4 tires.. and it works instantly..and lasts ,, well in my case ,, forever. none have failed.
I was told that 3 car mfgr are substituting a slime pkg instead of supplying a spare tire. the kit comes with a bottle of slime, hoses, and compressor to pump in the slime and inflate the tire.
I have a vac pump.. so I measure out the slime,, put it in a camping ketchup squeeze bottle .. vac the tire,, pinch the hose, pull pump off and poke the nose of the ketchup bottle into the hose,, and it slurps it in!
Fill tire ,, spin it a couple revs.. and tire is sealed.
most obvious place I used slime is floatation tires on 3 wheelers.. we would get punctures every time out... but with slime in there.. you didn't even know.
I learned of the stuff years ago ,, from a C A A driver.. he came into our parking lot,, turned his front tire so he could puncture it... air blowing out.. he backed up so the tire turned a few revs.. then brought the car back to same point to view hole sealed.. amazing!! and he had done this soooo many times, the tread almost looked GREEN ! ...
but realistically,, for a road tire.. you will only experience a few punctures ever.
Large 4x4 tires arn't my favorite.. i usually put the slime in when the tire is leaking... and i put a lot less than the mfg recommends.. because in cold weather,, it seems the stuff puddles, and freezes,, and then your truck goes down the road ,,, thump thump thump for quite a few miles..
my honda shadow has wire spoke wheels.. a spoke liner , and tubes.. they slow leak... so when I put on new tires, new liner and new tube and both front and rear continued to slow leak... i put a small amount of slime,, about 25 percent what the bottle calls for... no more leaks!
