Remetallizer (metal restorer) is lubricant for engine restoration without disassembling.
Remetallizer is lubricant based on nanotechnology. It contains material with metal particles, usually it is copper, bronze, and tin alloy. Copper itself is not used and it is oil oxidation catalyst.
The most known representatives of this group are RESURS manufactured in SPb (Russia), ENGINE RESTORER manufactured in USA, Metall 5 manufactured in France.
As for any lubricant the efficiency of remetallizers depends on the size of particles. The smaller the size - the more a particle is active.
Unlike geomodifiers, metal particles do not break heat exchange of the engine.
