ما هي مدة بقاء زيت البوليكس؟

Could you elaborate on the durability of Polyx oil, specifically in terms of its longevity? I'm curious to know if this product is designed for short-term use or if it offers a longer-lasting solution. I've heard various claims regarding its durability, but I'm interested in hearing your professional opinion on how long Polyx oil typically lasts under normal conditions. Is it a one-time application that lasts for several months or a more frequent application required to maintain its effectiveness? I'd appreciate any insights you could provide on this matter.
