    Thanks to Mother Nature, and a moderately damaging hail storm, my camper trailer suffered some damage to the 2 roof vents, with some fairly large chunks completely knocked out. I had already replaced the roof vents in 2017, due to a worse hail storm, and wanted to consider an easier fix. So...I used Titebond glue to adhere strips of drywall repair mesh (comes in a long roll, like drywall tape) over the gaps and to stabilize the multiple cracks. I put a small piece of painters' blue masking tape on the inside of the vent where the mesh was open to the interior, as I couldn't find a good size chunk of the roof vent plastic. The following day I used the Flex Seal Max spray over the entire surface of both roof vents. I sprayed it on very thick, to completely cover the mesh tape. The consistency of this product is obviously thin enough to produce an easily-sprayed product, for better aesthetic coverage, but it was probably a bit too thin for my application. I also used a 2" disposable foam brush to try and get thicker coverage over the mesh taped areas, once the product had started to set-up. The product's solvent evaporates fairly quickly, so I made another spray pass over the hand-brushed areas for better looks, and in case I had disrupted the coverage, to avoid leaks. The job looks great and appears to be adequately sealed. I'm also hoping that the 'rubberized' coating may be more hail resistant. Plastics at Denver's altitude take a real beating from UV exposure, so I'll see how this idea pans out. This spray also may be a good idea as a preventative to avoid moderate hail damage. Update: after waiting several days for the Flex Seal to cure, I tried to remove the small strip of blue painters' tape from the inside of the roof vent. The Flex Seal stuck to it pretty bad, and stripped off a little of the product. Luckily, I still had some left in the large, 17oz can, and made another pass to seal off the few small holes. Hopefully I'm now done with this project!

    I'd used the white flex seal on a wood bulkhead cellar door. It has worked incredibly well. The wood under neath is still in pristine condition 10 years later, but it needed a refresh as it was getting dirty looking, so I was excited to see that now Flex Seal comes in brown, I did not expect it to match other dark brown trim, but, wow I did not expect it to be this color!! It is more like a greenish olive bronze shade not true brown.I highly recommend Flex Seal their products are AMAZING - but if you are looking for a true brown shade, I recommend painting with the color paint you want and then applying the clear Flex Seal over the paint, as their website suggests.

    We live in a 80 year old home. This has help with drafts in many ways. I would recommend this over plastic on my windows anyday.

    3.0 out of 5 stars Observations and a few things I wish I'd know before purchase.

    S. · May 29, 2016

    This review isn't really testament for sealing roofs, or screen doors against water. I purchased this to use more as a "rubberizing" and water barrier sealing spray. I wanted to use it to seal some raw steel to protect and prevent it from rusting out in the garden. So far it's done it's job of sealing out water, but it also looks like plastic coated metal, rather than metal with a clear coat. I'm going to leave it for now to see how long it prevents rust, but eventually plan to remove it and try something else that looks more natural.Some other things I wish I had known before buying that might be helpful to you:> It does NOT have a "delicate" nozzle tip. When you spray this, it sprays out fast and hard. There's not much "feathering" you can do.> As it sprays, some of the overspray will turn into little airborne rubber "floaters" that have a tendency to drift much farther than just regular over-spray. It's almost like little gossamer web tendrils. So make sure you take this into account.> There are other spray rubber products that are available that act much more like spray paint. They are meant to coat and not really seal with the tenacity of this Flex Seal. — That's not to say that Flex Seal, doesn't do what it's advertised to do — I'm just saying that if you're looking for something to use to create a smooth rubberized coating on something, you might be better off with a different product, Like Krylon.> the price was better for this than other rubber coating sprays, (which I have not had much luck finding in my local Home Depot or Lowes stores)>As a water sealer for cracks — I also tried to use this on a large, clear plastic rain gauge that had developed some small cracks, resulting in a slow leak. I sprayed several coats of the flex seal on it. It didn't work. And because it doesn't have a very smooth or fine spray, it went on with such a dimpled effect, that I couldn't read the numbers through it.Maybe it works on roofs and turning screen doors into boat keels, but it didn't work for me for sealing small cracks to prevent the force of a couple ounces of water at bay. It might have been different had I tried to spray it into the inside of the rain gauge. But seriously, thing about it... you're just not going to have any kind of permanant effect on a roof repair, for instance. As a stop-gap measure, maybe.

    La calidad del producto y su eficiencia.
