Seal Your RV Bumper

The video demonstrates using Flex Seal aerosol (black) to restore a rusty back bumper, making it look brand new by coating, protecting, and stopping rust bleed.

Surface Preparation:

The most important step is proper surface prep. You don't need to remove every piece of rust - just the loose material. Use a scuff pad to take off surface rust and anything loose, then clean with denatured alcohol and a microfiber rag. Some rust can remain attached to the bumper as long as all the loose material is removed. A clean surface is essential for Flex Seal to do its job properly.

Application Technique:

  1. Shake and test - Shake the can well, then do a test spray away from the surface to clear any solvent from the tube
  2. First coat (light) - Use long sweeping strokes, staying in motion. Don't sit in one spot too long and keep the can at a distance (not too close). Apply a light base coat that allows some rust to peek through - this helps it grab onto the bumper and rust better
  3. Touch test - After a couple minutes, touch the surface. When it's dry enough, apply additional light coats
  4. Additional coats - Always be in motion before pulling the trigger to avoid blotchy spots. Continue building up light coats until full coverage is achieved

Pro Tips:

  • Multiple light coats work better than one heavy coat
  • Always start moving before pulling the trigger
  • After finishing, turn the can upside down and spray until it runs clear to empty the nozzle and prevent clogging

Result: The bumper transformation is dramatic - going from rusty to looking brand new in just minutes, and it's rain-ready once dry.

Fix Your RV Slide-Out Roof

The video demonstrates repairing a torn membrane on an RV slide-out roof that was damaged by a tree branch. The tear exposed raw wood underneath, creating a serious water damage risk that needed immediate attention.

The Repair Strategy: A triple-layer repair system using Flex Glue, Flex Tape (8-inch), and Flex Liquid to ensure a permanent, waterproof seal.

Step-by-Step Process:

  1. Clean the surface - Remove loose debris from the damaged area (doesn't need to be sparkling clean)
  2. Apply Flex Glue - Create a barrier around the entire perimeter of the damage, then glue down the torn flap. Use a putty knife to press it into place. The rubberized glue has instant grab and creates the first layer of protection
  3. Measure and cut Flex Tape - Measure the damage area and cut 8-inch Flex Tape to size (note: use a razor knife on a wood backer, not scissors, as the thick adhesive will gum up scissors). Use a blade to lift the liner corner for easier removal
  4. Apply Flex Tape - Align the bottom first, press down one end, then pull slightly for tension and lay down evenly. Use the tape roll to apply pressure and eliminate air bubbles. Pay special attention to corners where water runs off
  5. Apply Flex Seal Liquid - Before opening the container, use a chip brush to clear product from the cap groove for future use. Brush liquid into corners and edges of the tape first (cutting in), then roll it over the entire repair area to seal everything together

Important Notes:

  • Do not retract the slide-out until the Flex Liquid is fully cured (wait at least 24 hours)
  • The triple-layer system (glue, tape, liquid) creates redundancy to prevent future leaks
  • Regular maintenance is key - the main RV roof was also treated with Flex Seal Liquid 1.5-2 years ago and has remained leak-free since

Result: A permanent, waterproof repair that will outlast the original materials.

Seal Your RV Windows

The video demonstrates sealing a window with Flex Caulk, a hybrid formula that's 100% weatherproof, doesn't require a caulk gun, and can be painted over (though it's clear enough you won't need to).

Key Steps:

  1. Prep the surface - Clean around the window perimeter with denatured alcohol (or soapy water if there are decals nearby)
  2. Important warning - Never seal the weep holes at the very bottom of the window frame. These factory holes let moisture drain out - sealing them causes water buildup and bigger problems
  3. Application - Uses the snap-and-save cap with trigger flow nozzle that adjusts product flow left/right. Start on full power to clear the valve, then apply using the "start low and go slow" technique around the perimeter (stopping before the bottom weep holes)
  4. Finishing - Smooth the caulk with either the Flex Gap Filler tool or your finger, then wipe off excess

Fix a Loose Panel in a Van

The video demonstrates a quick repair on a work truck using Flex Tape Clear to fix a loose panel that's missing its clip.

The Problem: A panel on the work van is loose and coming apart because the retaining clip was lost.

The Solution: Apply Flex Tape Clear to the sides of the loose panel to secure it back in place.

Application Process:

  1. Identify the loose panel that needs securing
  2. Apply Flex Tape Clear to the sides of the panel where it's coming apart
  3. Smooth out any bubbles that form during application

Results: The tape appears clear and virtually invisible, and the panel is now secure and no longer coming off.
