I couldn't coz I have to strip the paint when it's sunny coz Te stripper only works when the temperature is proper hot. And I only sand it down manually too
after i removed the paint i just sand it down i used the finest one. but you could get that shine too just ask someone who knows how to paint they should know what to do with it or ask someone knows how to anodise they can do it too. but yeah i just polish it by hand. no coated or what so ever
