Carriers

Right gentlemen, as I mentioned before I bought another 300, this one very low miles and one owner from new. It rides likes brand new out of the box, lovely machine. However, both front and rear carriers have been chipped and scratched from general use and i want them looking new again (or very close). I could shot blast them and repaint but we all know it will chip off again, so, what you people coating yours with? Powder coat ? Bed liner? Anything I’ve not heard of ?
