What I was remembering is something that came in a tube the size of a tubular cement tube with a screw-on needle that had a hole at the tip and another one on the side. One would insert the needle into the tire, squeeze the tube, forcing the sealant out the hole on the side, rotate the needle while squeezing to distribute sealant around the edges of the puncture, and then as the needle is withdrawn, the tire casing would stop any more glue from coming out the side needle hole and force it to come out of the hole on the tip. This would plug the puncture as the needle is extracted. It was a quick and neat process. I used it a few times in the early 80s and it seemed to work fine for punctures (not tears). It was small and easily stored in a pocket or tire bag. Anyone else remember this, or am I dreaming?

Kevin -- That 'nasty goop' is just that, and permanent to boot. Once its in, its in for good, rendering future repairs unlikely. Besides, if one has room for a can, why not another spare instead?
