Designed to solve the #1 pain point of homeowners: leaks that keep coming back. Ruscoe HV bonds aggressively to aluminum and steel, works even when submerged in water, and stays flexible for over a decade. Whether it's a dripping seam, a leaking corner, or a loose end cap, Ruscoe HV fixes it for good.
★★★★★ The Only Sealant That Actually Works
"I've spent hundreds on silicone and 'gutter repair' tubes that peeled off after one winter. Ruscoe HV is in a different league. Applied it in the rain to a leaking corner, and it stopped instantly. Two years later, it's still solid as a rock." - Mark T., Verified Buyer

SOLVING YOUR GUTTER HEADACHES
COMMON LEAK PROBLEMS SOLVED
THE PROBLEM: Wet Weather Leaks
Pain Point: You only notice leaks when it's raining, but most sealants require a bone-dry surface to work.
Ruscoe Solution: Ruscoe HV loves water. You can climb up safely during a break in the storm and apply it directly to the wet seam. It displaces the water and bonds instantly.
THE PROBLEM: Failed Silicone
Pain Point: You've re-caulked the same corner three times. The silicone peels off like a rubber strip after a year.
Ruscoe Solution: Silicone doesn't bond well to oxidized aluminum. Ruscoe HV is adhesive-based; it chemically grips the metal surface for a bond that requires tools to remove.
THE PROBLEM: Expansion Cracks
Pain Point: Metal gutters expand in summer and shrink in winter, tearing apart rigid sealants.
Ruscoe Solution: With a service range of -40°F to 200°F, Ruscoe HV stays elastic. It stretches and compresses with your gutters, maintaining the seal through every season.
APPLICATION GUIDE
HOW TO APPLY LIKE A PRO
Preparation:
- Clean: Remove old caulk, dirt, and debris. A wire brush works best.
- Dry (Optional): While it works wet, a dry surface is always optimal if possible.
- Temp: Best applied between 40°F and 100°F.
Application:
- Load cartridge into standard caulk gun.
- Cut nozzle at 45° angle for desired bead size (1/4" recommended).
- Puncture inner seal.
- Apply generous bead to seam, corner, or end cap.
- Tool (smooth) the bead with a spatula or gloved finger to ensure contact.
PRO TIP:
For the ultimate leak-proof joint, apply Ruscoe HV to the inside of the gutter seam AND a thin bead on the outside. This creates a double barrier that water cannot penetrate.
