Review: Love this stuff!! - Love this stuff! Was able to use it to help seal various different parts on my 69 Dodge Dart Project. Has a nice glossy texture and dries pretty quickly. Helps protect my components in my car and keeps them from cracking. It is a good texture for most any projects. I have used it on other applications too. It's nice that it's a versatile project that I can use for almost anything!
Review: Worked great - 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 and discolored, 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!

## Questions & Answers

**Q: Could I dip wooden chair legs in this to prevent them from scratching a wood floor?**
A: Yes, you can dip wooden chair legs but as you use the chairs the bottom will wear off. If they were my chairs I would use felt pads that you can find in any hardware store.

**Q: Would a metal surface become insulated electrically after this was applied? Thinking of a tight car battery compartment...**
A: Not enough to protect the battery from eventually shorting out. I would recommend securing a thick piece of rubber between the battery terminal and the metal close to it.

**Q: How long dose this take to dry**
A: It takes at least 24-48 hours for Flex Seal Liquid to dry based on the thickness of your application.

**Q: My child has a basketball post with a plastic base that holds water.  The base has a leak. Is this product suggested? If so, any prep suggested?**
A: Anything works better with a little prep., sandpaper and clean.  It should do well.  Also as a add the new tape would probably work better.

### ⭐⭐⭐⭐ 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.
