    5.0 out of 5 stars Works well and can reuse the product after you open the can.

    This product is thicker than paint and can be messy to apply. I did not want the spray Flex Seal because I could not control the over-spray on the pipes I was coating with the product so I chose the can Flex Seal to brush on instead. Can cover in one coat. I used this to seal exterior pipe insulation which is a semi-porous material, but it still sealed in one coat. If you apply this can Flex Seal by brush as I did, after say 5 minutes do not try to reapply more Flex Seal to the first coat or the first coat will just peel up on your brush. Follow instructions on the can for recoat. If you don't use all the Flex Seal can product just place the lid on it and it will form a top seal inside the can (just like oil-based paint does). Once you open the can back up for another use, simply break the top seal and the rest of the Flex Seal in the can will be usable.

    5.0 out of 5 stars Works great for my purposes. That is to keep things from sliding around.

    Two or three years back, I 3D printed some drink coasters to use. But one problem was that they would slide easily.So I ordered Flex Seal in this week to try coating the bottom of them creating a non-skid surface.It takes 48 hours for this stuff to cure completely. But after 24 hours with my 1st test, it appears that I am getting what I wanted. A non-skid surface on the bottom of these coasters.The stuff states that it can be used as a sealant. But there are many products that can be used as a sealant, and this 48 hour cure time is a drawback. 24 hours before it is safe to handled.It also states that it can be used as liquid electrical tape. Again, I agree with this. But that curing time is a drawback.But for coating surfaces, it is a winner in my book. (So far....)Update: April 9, 2018The stuff worked great on the PLA plastic coasters. PLA plastic is a material made from corn.However, I had 3D printed 1 coaster with ABS plastic with a rough base. ABS plastic is the stuff used in cars. Here the Flex Seal appeared to cure in 24 hours. However, that coaster required 2 coats of Flex seal because it had soaked into the plastic..Having used my coasters with the Flex seal bases for a few days now, they work exactly as planed. Put a cup in them with any liquid, and they are planted and un-moving. They won't slide off of a table without a lot of help.I suspect that this application would work for many materials where you don't want them sliding around.(Hmmmm...... I wonder if I can make some non-skid pads under my old laptop? Maybe the same thing for my sound speakers on my desktop or TV? It's an idea...)

    Purchased this product for use on my travel trailer. It is awesome. It went on smooth with a roller and provided a nice leak free finish.

    The ease of use came to mind since I bought this .I had a seat on my lawn tractor that was torn worn in several places got tired of wet seat cushion I'm at wits end when I thought about that foam cushion soaking my butt so I tried this and boy was I surprised easy application roughed up surface cleaned with gasoline before applying a low and behold looks like a new seat now applied with a brush several times to get it right but we'll worth it,matter of fact did 2seat cushions takes about 24 hrs to cure But it works you won't be disappointed!!!!!

    As can be seen in the photo it looks like this box was thrown around and dropped several times. Flex seal is a great product but shipping made this go through a ringer

    This did what I expected. I have a 1976 Volkswagen Beetle convert. that I am fixing up. The rubber on the running boards was dried out anddiscolored, along with some splits in the rubber showing bare metal underneath. It was going to cost well over two hundred dollars each to replace them, so I thought I'd try Flex Seal. After cleaning and drying the running boards I applied the product with a small paintbrush. It went on easily,covered really well, and small "oops" we're easily wiped up with a cleaning cloth. I allowed a drying time of 24 hours and just now went out and filled in the split areas with a little more product and smoothed it out with the brush. It looks fantastic! I took a couple pictures which don't do it justice. It dried really shiny, and looks wet although it's dry and looks and feels like rubber.Some tips: I first stirred it very well because I could tell it was thick at the bottom of the can. It was easy to stir up though. When I was finished with the project yesterday, I replaced the can lid and tapped it on tightly. My brush I wanted to use again for today's touch up, so I sealed it in tin foil. When I opened the can again today it was ready to go but is tired it again anyway. There was no "skin" on top, and no lumps. My brush was only slightly stiff and I was able to use it again. I used about half a can of the product to do both running boards and am very pleased with how they look!
