Left untreated, corroded areas quickly become extremely expensive to repair. They will certainly diminish the value of your aircraft.
Corrosion is simply oxidation.
It happens whenever metal and moisture come together. It can't be stopped permanently but it can be controlled. The most effective way to control it is to get rid of electrolytes that cause it. No Moisture - No Corrosion Corrosion X takes corrosion control to a new level. Corrosion X penetrates through any oxidation, displaces electrolyte and leaves behind an ultra-thin fluid film that stops electrolysis.
