There’s something satisfying about making DIY repairs on your vehicle, and The Flex Seal Family of Products helps make those wins possible. With tough, dependable protection and easy-to-use solutions, you can take on automotive repairs to keep your car looking and performing its best. Here are 4 simple auto repairs you can make with Flex Seal products.
1. Secure Automotive Stripping with Flex Shot
Weather stripping, trim, and exterior detailing can loosen or degrade over time, allowing water to seep in and cause damage. Flex Shot is a quick solution for resealing these vulnerable areas. Its precise nozzle and extension tube allow for accurate application, even in hard-to-reach spots. Once dry, Flex Shot forms a weatherproof, flexible barrier that seals out moisture, air, and water, making it perfect for automotive leak repairs. It’s a must-have for preventing issues like rust, mold, and mildew before they start.
Flexpert Tip: Flex Shot’s extension tube can be cut to any size to produce your desired bead thickness.
2. Fast Bumper Fixes with Flex Tape
Cracked bumper? Slap on some Flex Tape! This heavy-duty waterproof tape bonds to almost any surface, including plastic and metal, and strengthens with pressure and time. Use a razor or box cutter to cut a strip of Flex Tape to the desired size, then peel off the backing and apply it directly to your damaged bumper or panel. Flex Tape’s powerful adhesive helps hold parts securely in place until permanent repairs can be made.
Flexpert Tip: For maximum coverage and sealing power, Flex Tape should extend past the damaged area.
3. Flex Seal Spray for Car Rust Protection
Rust can quietly destroy vehicles from the inside out. Stop the damage with Flex Seal Spray. It forms a flexible, waterproof layer that defends against corrosion, salt damage, and everyday wear. Spray Flex Seal in hard-to-reach areas like undercarriages, wheel wells, and trunk seams to stop leaks and rust before they begin. Whether you drive through snow, salt, or sandy terrain, Flex Seal helps provide long-lasting car rust protection where it’s needed most.
Flexpert Tip: Flex Seal Spray should NOT be used on radiators, tires, or other areas with extreme heat and pressure.
4. Waterproof Your Truck Bed with Flex Seal Liquid
Truck beds can take a beating, especially if you lug heavy gear or tools. Flex Seal Liquid is a waterproof liquid rubber coating that can be brushed, rolled, or poured onto surfaces to protect them from abrasion, weather, and UV rays. Flex Seal Liquid creates a watertight truck bed liner that’s flexible, mildew-resistant, and built to last.
Flexpert Tip: For an even more durable finish, apply multiple coats for added thickness and protection. Make sure to wait 24 hours between coats and 48 hours for Flex Seal Liquid to completely dry.
The Flex Seal Family of Products makes it easy to take automotive repairs into your own hands. From spray sealants to liquid rubber coatings, Flex Seal can help keep your ride in top shape, mile after mile.
