HM Hammerite 2x 600ml Underbody Vehicle Seal With Waxoyl Black Underseal Aerosol Can Kills Rust Prevents Reappearance heavy-duty protection Flexible weather proof skin

HM
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.
  • The thick waxy liquid is saturated with a very powerful rustkiller and it chases out moisture to form a flexible weatherproof skin that wont crack, dry or wash off in the rain.
  • The rust-inhibiting molecules in Waxoyl cut through films of oil, grease and dirt in seconds and cling to metal surfaces and unlike chemical inhibitors used in ordinary rustproofers, they stay active indefinitely. If the skin is scratched or punctured Waxoyl creeps back and reseals itself.
  • Waxoyl is ideal for the insides of doors, behind sills, chassis and anywhere that water is likely to collect
  • Hammerite Underbody Seal gives heavy duty protection for underbody, wheel arches and other high impact areas.
