Is it true that powder coatings can withstand any conditions and can even be applied to rusty metal?
Unfortunately there is a myth that since powder coating is so much easier to apply than wet paints, and retains a very hard film, that powder coatings can withstand anything and everything. Indeed this carefree view has led to some disappointing applications of powder coatings. Powder coatings rely on a clean, pretreated surface like any and every other coating. Rusty metal deposits must be removed prior to powder coating, as over coating with powder will only mask what is fundamentally corroding metal. Powder coatings are terrific in resisting knocks and abrasions, chemicals and the effects of the sun, but if not cared for, the coating can show up scratches and perhaps film integrity loss.
