Apparently they're just the thing you need if you have a few loose fillings you want out!

tried them twice great but very hard on the body

Basically, there are two kinds of puncture protection liquids. The first
kind works solely mechanically. The liquid contains small fibres or
particles that will close the hole. Advantage: Such liquids can stay in
the tube for an unlimited amount of time. Disadvantage: The hole is not
really repaired but only plugged and it can open up again e.g. the next
time, the tire is inflated. The second kind of liquid is latex based. It can
be recognized by its distinct ammonia smell. When latex contacts the
air, it hardens and in that way it permanently repairs the hole.
Unfortunately, these kind of liquids can only stay in the tube for a
limited amount of time before they cure completely

In addition, if you get a puncture that is too big for the sealant to cope with, it's virtually impossible to get a patch to stick to the tube. This may happen if you lose some pressure before a puncture fully seals, then hit a pothole and get a snakebite.
