Conclusion - Does Mighty MendIt work?
So, does Mighty MendIt work or not? Mighty MendIt is a pretty good bonding agent, if you take into account the rules. However, the rules are stricter than you are led to believe, and they make using the product unsuccessful if you do not follow them. I have used another fabric bond before, and on material, it performed better than the Mighty MendIt. I think there is a relationship between how stiff the materials are that are being attached, and how well they attach using Mighty MendIt. The stiffer the material, the better it works, as does using it when both surfaces are non-porous.
It might work pretty well for hemming up the bottom of jeans, but on dress material, it did not work as well as advertised. I think for the material to remain completely flexible, the stream of Mighty MendIt needs to be very thin, and on porous material, that does not give it a solid grip between the two surfaces. When the layer is thicker, you start feeling stiffness from the Mighty MendIt.
You also need to take precautions, as it is dangerous to breathe the fumes, have it on your skin for too long, swallow it, or expose it to flame in a liquid state.
I certainly would not trust myself to a parachute bonded with this material, and I would not use it on clothing that I was fond of. However, I have been sitting in the leather chair I mended a week before I wrote this article and I think it did a very satisfactory job on it. I do not think I would order it online, unless it was in a special shipping deal from Amazon. Try it if it sounds useful, but look for it locally.
