TWIST & LOCK! so simple. Put this on the Habanero Cordless Heating Tool give it 20 seconds and start stacking dimes! It is so easy to fix a plastic piece that has a crack or some damage. Use this in combination with the Hot stapler tip and you will have a better than an original joint. USE this to fill/repair open body panels, repair aftermarket parts or fix headlight fixtures broken in an accident or from old age.
