Review on Harzole TS-4V50 Gray Gum Poly Wrapped Inserts: 4" Length Tire Repair Plugs (50pcs/Box) by Eric Fish
Look from the outside, but don't.
So I begin I am an auto technician with 30 years of experience and have sealed hundreds of tires with a 99% success rate. I've used 15 of these plugs in 4 different tires and maybe 1 plug held air. I've changed several times and put 2 in 1 hole and still left air. I even tried a different type of rubber glue and the same result. Stay away.
Pros
- Tools and Equipment
Cons
