you must take care of it to keep the shine also
What do you mean? Will it lose its shine and look like it did before? Or does it just get kind of dull looking? Will a little chrome polish get it back? Or do you have to go through the whole process again?
Part of the reason that people get things chromed is because it is easier to maintain than polish. Wash, dry and be done. Think back to the days when folks had large family gatherings and got the special china and polished utensils out. They had to be polished just like your frame. I use Mother's polish on mine and it works great. Again, just takes some time to keep nice. Can't go back to the stock look, but will dull and haze over.
