Slime tube sealant, has anyone tried tube sealant on small inner tubes?

Although you've got to remember that Stans solution will not seal instantly in colder temps like today.

Had some stans in a pair of (tubed) CX training wheels that I used on a road ride last Saturday. It was cold. I punctured. Sealant did not work so just replaced the tube. Popped the tube with the sealant into my jersey pocket. When I got home, it had sealed nicely. I'm wondering if had it been a few degrees warmer I'd have been fine?
