Check out the best auto repair tips by real Flex Seal fans!

There’s no type of automobile that you can’t repair with Flex Seal Family of Products – ATVs, trucks, convertibles, and classic cars are just some to name a few. We took our products to the streets and asked our Flex Fans to put their favorite ones to the test. These are some of the best auto repairs with Flex Seal products that they came up with.


1. Customize Your ATV with Flex Seal.

If you’re a true ATV rider, you know that those vehicles can really take a beating. Freshen up the color and make your favorite off-road vehicle shine like new with Flex Seal Colors.  Check out the Flex Fan submission below of a repaired child’s power wheels quad. This fan searched long and hard for a product that could change the look of his son’s favorite toy and withstand any kind of outdoor terrain. Luckily, he found the perfect sealant spray for the job – Flex Seal Blue.

2. Use Flex Seal to Revamp Your Car’s Exterior.

Take this auto repair tip from one Flex Fan who truly loves to take his Jeep off-road. In order to smooth out a lot of existing rock chips on the rocker panels of his Jeep, he used Flex Seal Black on the rocker panels. He was so impressed with the results that he decided to use Flex Seal Black throughout his entire vehicle. Take a look at the image below –the parts in black have been sealed with Flex Seal.

7. Got Rust on Your Vehicle?

Did you know Flex Seal can actually prevent rust from the beginning? As a sealant, it helps to block out moisture, which keeps the rust at bay. This 20-year-old car had rust on almost every surface. Once the rust had been cleared off completely, Flex Seal was applied to all the affected areas. This car owner told us, “Flex Seal is the best solution I’ve found!”
