### ⭐⭐⭐⭐⭐ It's great

### ⭐⭐⭐⭐ A little expensive, but it does the job.
*by G***R on April 6, 2026*

I used this on a steel trash can that I store bird seed in. The top had a gash in it and no matter what I did, water would get in and ruin the seed. I hated to throw it away since that was the only problem. A can of this, and the problem was solved. It's a little spendy for the amount you get which is why I removed 1 star. But there's no question it works good. My only other gripe is that it takes a long time to set up and dry. So if you can keep your project level and dry for 24 hours, that will go a long way to helping it cure. I just used a disposable paint brush to apply it and I kept the now hard brush for future applications. It's fairly durable depending on what you're trying to accomplish. I tried using it on the feet of my deck chairs hoping it would save wear and tear on my deck? Not a good idea, it just fell off after a couple of uses. But for sealing, this is a good product.
