Rogard Supreme Seal 500 is a clear coating to be used over zinc coated, zinc plated and passivated zinc surfaces as an improved corrosion protectant. It works equally well on zinc and zinc/nickel alloy that is either electroplated or mechanical plated.
 
Rogard Supreme Seal 500 offers up to 500 hour protection from red rust during a salt spray test drastically increasing the corrosion resistance of chromated zinc coatings. It contains no volatile organic compounds and is easy to use and control.
 
This sealer will give the best corrosion protection when used in conjunction with a zinc passivate. It can however, be used on pure zinc as a replacement for a passivate.
 
Mixing and usage instructions are included.
