It Does what it says it does! Very Easy application, nice texture, pretty good on curing time. I would definitely purchase again when the need arises.

Fantastic product for so many different projects!

3 months ago
The handle on our microwave broke and I had just received this sample. What better use for it right? Well let me tell you what a fantastic job it did! You’d never know the handle had broke. It has a strong seal after curing. There was no mess and it didn’t even smell terrible. I plan to use it any chance I can to see all the different uses I can get out of it. But it is definitely strong. I don’t think any other product would hold as well with all the kids tugging on it.

Easy and strong!

The ultimate putty is super easy and super strong. I have used this for both big and small projects and it hold up great! My only complaint is that it does dry quick. Be prepared and ready to go!
