Mastercoat Inner Panel Protector (Extreme Elements Corrosion Inhibitor) is a highly concentrated rust inhibitor that is ideal for applying into any type of cavity or hard-to-reach area, such as rocker panels and where two pieces of metal are welded together. It is also excellent for protecting brake lines. This can be used in conjunction with Mastercoat Rust Remover & Descaler, and MasterSeries Permanent Rust Sealer. This coating, unlike the silver sealer, and other moisture cured urethanes, is more user friendly in the sense that it can be removed with mineral spirits and generally will not harm painted surfaces. Can be removed with wax and grease remover immediately without damaging the paint. This coating has an extremely high resistance to salt spray. Spraying: just reduce with mineral spirits and apply with a wand sprayer. Brushing: full strength out of the can.
