I have used a type of goop shot into the tire to prevent flats, I've used CO2 inflators on the side of the road, and now, I have a small electrically powered compressor I will use along with a BMW type repair kit. CO2 types worked, kinda. After a VERY sharp learning curve 150 miles from home and maybe 50 miles from anywhere, I used two of the three in the kit I had to kinda get some air into the rear tire and limp, literally, to the nearest gas station to put some more air into the tire. I was headed to the national in CO from OH in a few months and I swore never to use something like that again. My experience only, many others will be different.
