Nice to have
[This review was collected as part of a promotion.] Easy to use.. I really like that it has the plunger to equally dispense each tube. It was a pretty clean and simple process. Definitely recommend and will use again. Only thing i had that needed fixed at the moment was my little skeleton and he’s good as new now 🙂💀

Small but mighty
[This review was collected as part of a promotion.] Needed a quick fix for a tile that fell down onto my counter. My husband didn’t have any issues with the use of the marine weld syringe. The packaging was the perfect size to keep in your tool box. It may be small, but a mighty product.

Not ready to sand in one hour, if temp is 50F.
Would Not RecommendThis epoxy does not perform well under 50 degrees F. Set time is much longer than an hour. It is not sandable in two hours, and showed poor bonding to wood. This product is very inferior to Starbond 5 minute epoxy.

Held up
[This review was collected as part of a promotion.] This held up well! It’s meant for boats or water activities that need mending because it can withstand those. Very effective and worked well in a pinch until I can repair the damage! package was great as it made it easy to use, effectively. Definitely recommend for quick repairs!
