I have ordered this blacktop filler every year and it has been great. Ordered 2 more tubes recently and both are bad. Had them replaced and both were bad. They are solid and the caulking gun can't push anything out. Do not buy!

Product is a little thick. Even after poking several holes inside the tube. Some effort is required to pump this product out using a caulking gun.

I bought a carton of 12, and they were ok, this stuff is always stiff. But then I ordered 6 individual tubes, and they were so hard I couldn't get any out of the tube even when squeezing with both hands. It broke my new $ 120. Battery caulking gun.

I wish I could submit a review without a rating, as I was unable to actually use the product. It had solidified in storage before being sent to me and it was almost impossible to squeeze any out of the tube. I have it sitting in a box awaiting pickup for return.

This sealant goes on very smoothly when applied, very flexible and it should last for a long time. The product comes in the color black ...other colors should be offered.

The first Tube of this Sealer I bought worked Great; and I filled a good size crack across my driveway. It flowed well and setup as stated. The second (separate) order for the same Sealer was bad. The entire tube was a solid mass. A received a refund; but since I needed to seal another driveway crack, I reorder it again. And again, it came in an almost solid mass.The Seller, Hardware City, could not explain or even guess what had happened, THEN, Amazon to the rescue. Amazon said it would resupply me a another tube with no charge. My guess is that this Red Devil product has a shelf life and that these were simply old tubes. I am hoping the laws of chance smile on me and I get a fresh tube...again.

Very good at sealing cracks in the driveway. I wait a month to allow the polyurethane to cure and then have the drive way sealed with tar. This approach helps to minimize the chance of water getting under the driveway and heaving it. Have a couple of disposable narrow putty knives handy because this sealer is very sticky and will ruin the putty knife so don't waste a good one. Using the putty knife and spreading the sealer along the crack makes for a professional appearance.

It works, is a little thick and takes a wider opening than I desired.
