Chlorine Resistant Masking Material/Film
I am working on a project in a Chemical plant where I am facing few problems. The process is of electrolysis in which caustic soda ⇦liquid caustic soda in bulk on Amazon [affil link] NaOH is produced from brine solution (NaCl + H2O) resulting in Chlorine atmosphere where everything is corroded. Now I want a masking/adhesive material/film that must be chlorine resistant that can protect front door of control panel having operator touch screen.
If you can help me in this regard I will be grateful.

I have had electrical equipment with gasketed access doors corrode badly outside (not inside), when in either a salt (NaCl), or acid (HCl) containing mist. We slowed it some by cleaning, and then coating all exposed surfaces with several coatings of Carnauba ⇦ this on eBay or Amazon [affil links] . This takes a lot of "elbow grease", but works, for a while.
