  • what a product - best buy so far for roof repair in the Texas Heat!!
This product is fantastic. It works like no product I have ever experienced. A bit expensive but worth it. Durable, easy to apply, quick to dry, and easy to follow instructions. I will need to complete another review after the summer and in a few months to test the products guaranteed sustainability and lasting outcome, after the Texas summer heat. So far, amazing in a two-month time after application. ... show more

  • There is a difference result other than the ads
Saw this product in ads. Bought one for trying. It does easily apply and use. So to buy the 2nd one. After one week after applying, the result is the applied surface is not hard as showed in the ads. It's more like a rubber surface. And also it is not good for vertical crack. The filling will not stay. It will drop down. This is not what I hopeful. ... show more

I bought this for some old Christmas outdoor inflatables that I have that just wouldn't stay inflated enough to stand up. Applied this with a brush and they stayed up like they were new again.
