    Color does not match
    Just be aware that the color is not a normal brown but much more olive/dark green. Otherwise worked as expected. Very thin applications and have to do several coats but then it was a good sealant for thinner cracks and chipped areas.

    5.0 out of 5 stars This stuff DOES work in an outdoor birdbath !
    Reviewed in the United States on July 23, 2023
    Style: FSBRNR20-2PKVerified Purchase
    After much time (say hours upon end) of searching for a product that would NOT harm birds that frequent bird baths that are made of a composite (resin) - this one did as such state - 'will not harm wildlife'. Found a deal and the deal happened to b thru Amazon. Chose the 'brown' which wasnt too bad considering I've sprayed the exterior in the past with a few browns/tans - this particular bath looks like stacked boulders up to its removable dish. The dish itself is what decays (develops minor cracks n' fissures) due to frost chills by myself not bringing it inside at signs of a first frost with water present. SO past several years I've had to repair that dish with normal vehicle fiberglas n bondo 'plastic' which doesnt look so great up close thou does work, just doesnt last from year to year as it breaks down from constant water exposure. Finally gave it a douse (3 coats thru time, several hours between each) - used a can + 1/2 of 2nd can) to complete - took inside and waited a few days then out to its always present location. Results - works ! Waited to do this review til a 3 month span has passed - Still 'brown' - Still waterproof - Still works ! AND ... birds are NOT harmed ! Good deal as that ol' guy in the boat boasts.

    Works good. Surface has to be clean before spraying or it won’t stick and just peel off. Shake it well it comes out super oily and must be sprayed
    In thin coats. Once it dries add more as needed and it works great

    Great stuff, flex seal. If you’re thinking this will be actually Brown, I need to re-frame your expectations.
    Rather than falling into the standard color wheel version of brown, the color of this product skews Toad.
    Meaning, it’s a muddy green
    I used it anyway, despite the horror, painting with a brown oil based paint to achieve the results I desired.

    I ordered a 2 pack. When it arrived things were hectic and I had to use it ASAP. It wasn't until 4 weeks later when going through my finances, that I realized I only received one can. I figured it wasn't worth it to me to say anything since I hadn't realized it until late. Lesson learned.
