  • STOP!!! Read this first...
Size: 1-gal
1st off...what a great product 👌 👏!!! ****BUT**** if the can arrives dented on the top you better use ALL of it once you open it!!! I didnt mind that the top was dented very badly bc it was still closed, but I only used about half of the $120 gallon and tried to put the top back on, was unable to due to the dents! I came back to use the other half 2 days later and it was a big cylinder of hard rubber, unable to use 😒...like I said tho, great product, but use it all if its dented or do not except it...(especially with the $$$ gallon can) and flexseal took amazing care of me after finding out what had happened! what a great product, with great customer service! wish i could give it an extra star!!! thank you flexseal... ... show more

  • Beats best expectations
Size: 1-gal
Many people told me this was a great product. I've used it two or three times now and it has far exceeded the best expectations that I could have going into it. I painted some things outdoors with it last year and saved my cracked up ac housing on my RV with it. Last week I sealed the entire roof of the RV with it as well. Just to let you know how well this stuff sticks- I got some of it on my leg I think that was Sunday. It is now Friday and I've been washing that spot on my leg with soap and water for a week and it still has not come off. I recommend reading the directions well, they have a website online- and having an assortment of three or four different tools to use for application so you can find the one that spreads it in the fashion that you prefer. Don't forget to cover the can after you pour some in your container for application. It does not do well with exposure to air in the can. I doubt I will ever not have some of this stuff on hand again. ... show more

  • Great Product that needs storage solution of unused product
I purchased this product to hopefully bandaid a problem with the PVC metal wrap on my house. 10 rolls of metal to cover rakes, windows, doors, etc. and EVERY ROLL HAS FAILED. The PVC is peeling off the metal, only 6 years after wrapping. To rip off the metal, rebend and reapply will not only be costly but painfully time consuming. Last year, I decided to look into rubber paint to hopefully stop what's already peeling from going further but could only purchase gallons, which are expensive so put it off. I was happy to find this product in a small can to test my theory. Yesterday, I cleaned off what was loose on 2 large windows, a garage door and the entry door to the garage. Wish I'd have taken pics of those but I didn't. The product is very thick and does not go on like paint, more like trying to paint with caulk. It covers nicely and self levels. You can only go a few inches with each dip of your brush into the can. It even sealed cracks in the caulk around the j-channel. Now for the drawbacks. I painted all the above with half a can of product, today it looked really good. I had hammered on the lid and started another 2 windows this afternoon. Where the liquid was missing in the can, the portion I had used missing, the Flex Seal had "rubbered" up around the can from the halfway point up and when I put in my brush, it would catch the rubber wads and they would stick to my brush. I've got tons of these rubberized wads stuck to my ladder where I had to wipe my brush to keep from getting on my window. Didn't like that and had to be very careful not to grab that with my brush. Mineral spirits DID NOT budge the Flex Seal on my brush, I mean it didn't even loosen it, melt it or dilute it. I threw the brush in the trash. As much as I hate chip brushes because they loose their "hair", it was a chip brush today and that too went into the garbage. The first pic shows what my windows, rakes, fascia are doing and two other pics are of freshly painted, still wet, hopefully-fixed-the-problem windows. I recommend only buying an amount you plan to use in a session. While painting on tonight, it was clear that the empty portion in my can was getting more rubbery as I used product out of the can. I don't feel I will be able to use the remaining 1/4 can tomorrow on another window as it continually gummed up, in this heat, as I was painting. ... show more

  • Almost as good as claimed
Size: 1-gal
While this stuff works pretty well it is not a "cure-all" and from my point of view, is overpriced.

  • Great material but hard to paint onto the surface .
Size: 1-gal
Very strong material . Fairly smooth and shiny . Went on fairly thick . But had little flecks of solidified material in the can immediately after opening it . I heard it was supposed to be paint thickness . Yet it was way thicker and there was a bit of solid material in the bottom of the can . So I'm thinking it was sitting in the can too long in the warehouse . I had the can unopened for just a few days before using it . So being so thick it spread like thick glue and was a beast to get to lay down flat with a brush . If I used a roller it would have been dimpled . It would not lay totally flat . So it ended up with paint lines in the dried surface . It did not shrink or smooth out after drying . It was hard as hell to get it to even touch down onto the surface it was so thick . It kept skipping across in spots . So I had to keep brushing back and forth just to get it to adhere . I assume I got an older can . Otherwise it would have been a bit more fluid and easier to lay down onto the surface . Which was mostly aluminum sheet . ... show more
