RUST & CORROSION PROTECTION 

What is the difference betweenRust Shield, Rust Mort and Rust Seal? 
     - The main difference between Rust Mort and Rust Seal is that Rust Mort must be top 
       coated and Rust Seal may be left exposed. Both will neutralize and convert the rust to a 
       permanent protective coating. Rust Shield is a rust and corrosion control coating 
       available in 14 different colors that can be intermixed. Rust Shield may be brushed, rolled, 
       or sprayed. 38008 Hardener and Gloss Enhancer may be added to Rust Shield to 
       increase the durability and add gloss.


I painted the frame of my vehicle with Rust Shield and now I want to top coat it. How long do I need to wait?
     - While we don’t recommend this practice, as long as Rust Shield has fully cured (3-7 
       days), it can be sanded and top coated. If the hardener has been added to the Rust 
     Shield
, it cures quicker and may be sanded and top coated when it is dry to the touch. 
       Again, we discourage sanding and top coating Rust Shield as it is a finish coat and not a 
       primer. If you have already applied the Rust Shield and intend on painting over, it must be 
       fully cured and it isn’t recommended.
