XCP Rust Blocker is a soft, anti-corrosive compound. It creates a soft,long lasting protective barrierto protect any steel, metal or alloy surface against the effects of rust and corrosion. Spray it, wipe it, brush it or dip it. A soft tack, that resists cracking. Depending on the level of protection required, coating thickness can be further reduced by buffing down if necessary. The bonding of the film with the metal surface will ensuremarket leading corrosion resistance. If used on coated and/or non-metal surfaces and parts, test on an inconspicuous area first.
