And because it is coming in the spray form, it doesn’t require any special skill. You only need to spray, and your problem will go away – whether it is a hole, a leak, or anything that can cause further issues. It would be easier if things are just that easy, but that’s not always the case.

And the cool thing about this spray is the waterproof feature and its resistance toward almost anything, like the weather. It sounds like a great technology, you may think. Unfortunately, real science isn’t that easy.

Using the sealant is pretty easy, really. How long does the flex seal last? The claim states that it should last for years, resistant to any weather condition, especially water.

If you are about to use it, you need to clean and prepare the surface first. Shake the can quite hard and press on the nozzle to let out the liquid. Apply and cover the area steadily. Apply several thin coats so it will cover the entire area. Wait for around 24 hours to let it dry.
