PLID float coat is the bulk fluid and method used to apply PLID rust inhibitor to difficult or unsafe to access voids, tanks, rudders, etc.  S2S PLID Float Coat has an attraction to steel much like a magnet.  It can be "floated" into or on water to coat those areas (sides and tops) that are difficult to access or apply a rust inhibitor coating.

A rust cell is similar to a battery; there is an anode, cathode and a path for current.  A transfer of electrons takes place causing reduction in the metal thickness.  S2S films eliminate the path for electrons (water for instance), scavenging oxygen from the surface leaving an ultra-thin, semi liquid, dielectric barrier coating that acts as a liquid insulator. preventing the transfer of electrons and thereby shutting down the rust cell.

S2S is not formulated to remove rust.  When applied S2S will stop oxidation 100%.  It will penetrate rust and corrosion scale to the base metal, loosening and easing removal.

No.  But, S2S is resistant to condensation and dampness to prevent rust and corrosion occurring.

Little preparation is required.  Ensure no loose debris present and apply.  S2S can be applied to damp surfaces - displaces water - and will penetrate existing scale.  Heavy flaky rust scale and loose paint should be removed as it will start falling off after a few weeks/months taking S2S with it leaving a dry, unprotected surface which may require a touch-up.

Yes.  S2S float Coat is dielectric to 40,020 volts and shut down electrolysis between dissimilar metals.

Yes.  S2S Float Coat is non-hazardous, non flammable nor toxic to fish in low concentration.  They contain only a small percentage solvent (9%) with 91% active ingredient. The discharge water is certified for discharge in the state of California!

Compared to blasting and re-coating the cost is less then 1/6th the price not including the lost time. Most areas can be treated for less than 50 cents per square foot!
