HM Hammerite 2x 600ml Underbody Vehicle Seal With Waxoyl Black Underseal Aerosol Can Kills Rust Prevents Reappearance heavy-duty protection Flexible weather proof skin
Why we love it
- Powerful rustproofing and moisture resistance.
- Reseals itself after damage.
- Ideal for high-impact areas.
Main Highlights
- Hammerite's Waxoyl provides excellent, all-round rustproofing treatment. Its unique formula solves the problem of hidden rust once and for all.
