Q:What's the difference between Powder coated frame; Pro-tec engineered aluminum frame and aluminum frame?

Firstly metals like steel rust very quickly and so need some protection if to be used outdoors where they will get wetHow ever aluminium is different , when aluminium gets wet , it oxidises and forms a dull coatingThis corroded coating how ever protects the aluminium underneath it so no more corrosion occursThis leaves a dull finish but it is weather poof and will last for years and years in all weathers, 20 years plus ! The chairs in the photo have a dry powder finish - this is a process where you heat up the aluminium to about 350 centigrade and then blow powdered plastic on to the hot metalThis melts the plastic and you are left with a plastic coated aluminium chairIts just cosmetic really as i said aluminium will not rust or corrode as it forms a protective film naturallyPro - tec is just some sales jargon for a professional protection against corrosion but its rubbish sales talk and just a cosmetic finishThe chairs look nice but aluminium does not rust so the plastic protection is not required !

Cosplay as AU Deidara perhaps? Like as if he was in a modern day setting? Or just Deidara without his coat, in his fishnet and t-shirt/tanktop? Pants are just black (sure you got that covered), and just wrap ace bandage (or whatever white cloth) around your lower legs
