Hammerite WaxOyl provides excellent, all-round rustproofing treatment. The unique formula solves the problem of hidden rust once and for all. 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. Specification: Finish : Black Size : 2.5L For use with the Hammerite WaxOyl Pressure Sprayer.
