10 Auto Repair Projects Using Flex Seal Products

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. Headlight repair with Flex Tape Clear

Your headlights (or headlamps) are very prone to breaking. After all, they are usually just a thin layer of plastic that are often subjected to rocks, debris, or other cars backing into them. When they crack, rain can quickly pool inside. With Flex Tape Clear, you can quickly fix the casing, to protect the bulb and electronics, preventing further costly repairs, while also letting light pass through. Be sure to check out Flex Tape Clear or stock up with convenient travel sized Flex Tape Minis.

2. Rocker Panels & Off Road Vehicles

Take this auto repair tip from one Flex Fan who truly loves to take his Jeep off-road. Some panels in your car’s exterior are meant to take on extra punishment, and are usually located towards the bottom or sides of the car. The rocker panels and undercarriage are a perfect example, designed to take on flying rocks that are kicked up by the tires. This Flex Seal Spray user applied a coat to the rocker panels on his jeep, to both smooth out existing rock chips, and to protect against future damage. He was so impressed with the results, he then decided to use Flex Seal Black throughout his entire vehicle. Take a look at the image above –the parts in black have been sealed with Flex Seal. You can purchase Flex Seal Black here.

3. Reseal the Trunk of Your Car with Flex Seal.

Here is a Flex Seal auto repair on a classic car. Some vehicles, especially older ones, have a metal trunk. Rust and leaks is a major hassle. This customer used Flex Seal Brite spray to coat the entire trunk of this 1966 Mercury Comet convertible for a crisp, clean finish. Take a look at the ‘Before and After’ photo. Not only does it help to keep water out, but it also looks much better with an even coat of Flex Seal. Flex Seal Brite can be purchased here.

4. Flex Seal Liquid – Tough Enough for a Tow Truck

Flex Seal Liquid pours out super thick, making it a great option for coating larger areas. One application is tool boxes.
These heavy duty tool boxes often take a beating, and are prone to water damage. Using Flex Seal Liquid helps protect the valuable tools inside, as well as protecting the surface of the tool box itself. But, don’t’ take our word for it. Check out what this Flex Fan had to say about it: “Flex seal is tough enough for our tool boxes on our 40-ton tri-axle tow truck up here in Maine!” Flex Seal Liquid comes in three sizes, and gallons ship free here.

5. Flex Seal on Fender Wells.

The fender wells sit right above the wheel, and like the rocker panels, the fender wells are one of the most susceptible areas of your vehicle to rocks and debris. In one fan’s DIY auto repair project, Flex Seal Black was used to coat the inside of the fender wells to protect them against rust on his vehicle. Another fan used Flex Seal Black on the rotted areas of the fender wells of his 1981 Mercedes, as seen in the image above. The spray makes it easy to apply to a hard-to-reach area such as this.

6. Protect Your Truck’s Bed Liner.

Over time, truck bed liners can really take a beating – that means rust, leaks, and erosion. If you find yourself in that situation, try using Flex Seal to protect it against damage. This fan above used Flex Seal Spray to touch up a corner with some damage. For more coverage, you could also use Flex Seal Liquid in your truck bed. Simply pour and spread to form a thick, protective waterproof barrier.

7. Got Rust on Your Vehicle?

Older vehicles tend to have problems with rust. Flex Seal can actually prevent rust from the beginning, or can help keep it from spreading. 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!”

8. Side View Mirror Damaged? Fix it with Flex Shot.

Cracks in side view mirrors can happen more often than you may think. An easy and reliable solution is to use Flex Shot to piece it back together! Flex Shot is dispensed as a thick gel, that dries to form a durable rubberized surface. Plus, it can bond pieces together. That’s exactly what this fan did. The Flex Shot not only keeps the pieces together, but it keeps water out, all with no caulk gun needed. You can shop for Flex Shot here.

9. Fix Gaps and Holes.

If you’re into NASCAR, you’ll enjoy this auto repair tip. JD Motorsports uses Flex Shot to seal off the gaps between the exhaust and the exhaust skirt. This technique has helped the Flex Seal Racing Team vehicles race faster on the track.
Even if you’re not a NASCAR driver, you can still use Flex Shot to fill in any gaps or holes.

10. Flex Tape Your Car’s Bumper for an Easy Repair.

Sarrah K. from Orillia, Ontario “I fixed my bumper, it’s been on there for a year!” Flex Tape super strength makes it a great option for repairing a bumper. Even if your bumper seems secured after damage, adding Flex Tape can help make sure that it stays secured in place.
